OPAx863A 器件是具有轨到轨输入和输出的单位增益
稳定、电压反馈、低功耗运算放大器,通过封装修整可
提供高精度性能、95μV 的最大输入失调电压和
1.2μV/℃ 的温漂,从而在整个温度范围内进行高精度
测量。
– 输入失调电压:95 µV(最大值)
– 失调漂移:1.2 μV/°C(最大值)
• 低功耗
– 静态电流:800 µA/通道(典型值)
– 电源电压:2.7V 至12.6V
• 输入电压噪声:6.3 nV/√Hz
• 压摆率:100V/µs
• 轨到轨输入和输出
• HD2/HD3:在20 kHz (2VPP) 时为–129dBc/–
138dBc
OPAx863A 器件每通道仅消耗 800µA,可提供 50MHz
的增益带宽积、100V/µs 的压摆率和 6.3nV/√Hz 的电
压噪声密度。具有 2.7V 电源电压的轨至轨输入级在便
携式电池供电型应用中非常有用。轨到轨输入级可在整
个输入共模电压范围内很好地适应增益带宽积和噪声,
从而在宽输入动态范围内实现出色的性能。

(1) Operation outside the Absolute Maximum Ratings may cause permanent device damage. Absolute Maximum Ratings do not imply
functional operation of the device at these or any other conditions beyond those listed under Recommended Operating Conditions. If
used outside the Recommended Operating Conditions but within the Absolute Maximum Ratings, the device may not be fully
functional, and this may affect device reliability, functionality, performance, and shorten the device lifetime.
(2) Continuous input current limit for both the ESD diodes to supply pins and amplifier differential input clamp diode. The differential input
clamp diode limits the voltage across it to 1 V with this continuous input current flowing through it.
(3) Long-term continuous current for electromigration limits.

8 Detailed Description
8.1 Overview
The OPAx863A bipolar voltage-feedback amplifiers offer 50 MHz gain-bandwidth product with a proprietary in-
package trim technology for high-precision performance with maximum 95 µV input offset voltage and 1.2 µV/℃
offset drift. The OPAx863A devices are low-power, rail-to-rail input and output (RRIO) operational amplifiers with
a voltage noise density of 6.3 nV/√Hz and 1/f noise corner at 25 Hz. The OPAx863A devices work in a wide-
supply voltage range from 2.7 V to 12.6 V and consumes only 800 µA quiescent current. The OPAx863A devices
operate with 2.7 V supply, are RRIO capable, consume low-power, and offer a power-down mode, which makes
them ideal amplifiers for 3.3-V or lower voltage applications that need superior AC performance. The amplifier's
main and auxiliary input stages are matched for gain bandwidth product (GBW), noise and offset voltage suitable
for applications which require wide dynamic input range and good SNR.
The device includes an overload power limit feature which limits the increase in quiescent current with over-
driven and saturated outputs to either of the supply rails. For more details of this overload power limit feature,
see 节8.3.2.1. The amplifier's output is protected against short-circuit fault conditions.
The OPAx863A devices feature a power-down mode (PD) with a PD quiescent current of 20 µA (maximum) with
a 3 V supply, with turn-on and turn-off time within less than 8 µs.

ZHCSOS5B –MAY 2022 –REVISED DECEMBER 2022
8.3 Feature Description
8.3.1 Input Stage
The OPAx863A devices include a rail-to-rail input stage. The main stage differential pair using PNP bipolar
transistors operates for common-mode input voltages from VS–– 0.2 V till VS+ – 1.6 V. The amplifier inputs
transition into the auxiliary stage using NPN transistors for common-mode input voltages from VS+ – 1.6 V till
VS+ + 0.2 V. The PNP and NPN input stages offer a gain-bandwidth product of 50 MHz and a voltage noise
density of 6.3 nV/√Hz. The offset voltage for the two input stages is matched to lie within the device
specifications. The auxiliary NPN input stage does not use the slew boost circuit during large-signal transient
response. The input bias current for the PNP and NPN input stages is opposite in polarity, which adds an
additional offset based on the values of the gain-setting and feedback resistors. A common-mode input voltage
transition between these input stages will cause a crossover distortion which needs to be considered in high-
frequency applications requiring superior linearity. Limit the common-mode input voltage to VS+ – 1.6 V
(maximum) for main-stage operation across process and ambient temperature.
Since the OPAx863A devices are bipolar amplifiers, the two inputs are protected with anti-parallel back-to-back
diodes between them, which limits the maximum input differential voltage to 1 V. The amplifier is slew limited,
and the two inputs are pulled apart up to 1 V when the anti-parallel diodes begin to conduct in very fast input or
output transient conditions. Care must be taken to use gain-setting and feedback resistors large enough to limit
the current through these diodes in such conditions.
8.3.2 Output Stage
The OPAx863A devices feature a rail-to-rail output stage with possible signal swing from VS–+ 0.2 V to VS+–
0.2 V. Violating the output headroom to either of the supplies will cause output signal clipping and introduce
distortion.
The OPAx863A devices integrate an output short-circuit protection circuit, which makes the device rugged for
use in real-world applications.
8.3.2.1 Overload Power Limit
During overload or fault conditions, bipolar rail-to-rail output (RRO) amplifiers consume excessive quiescent
current (five to seven times) with saturated outputs. With saturated outputs, the output signal is clipped with
much higher base current from output pre-driver stage causing increase in device quiescent current. During this
condition, the negative feedback control is disabled and an input differential voltage appears thereby resulting in
an input overdrive. During input overdrive, the slew boost circuit engages to increase tail current which further
increases device quiescent current. This overall increase in quiescent current can cause excessive battery
discharge in portable products shortening operating lifetime or disturb the thermal equilibrium causing
irreversible damage due to increased system power dissipation in a multi-channel design.
The OPAx863A includes an intelligent overload detection circuit. This circuit monitors for output saturation and
limits the base drive from output pre-driver circuit and disables the slew boost circuit in this condition. As Table
8-1 provides, this feature limits the increase in device quiescent current to much smaller values.

8.3.3 ESD Protection
As 图 8-1 shows, all device pins are protected with internal ESD protection diodes to the power supplies. These
diodes provide moderate protection to input overdrive voltages above the supplies. The protection diodes can
typically support 10-mA continuous input and output currents. Use series current limiting resistors if input
voltages exceeding the supply voltages occur at the amplifier inputs, which ensures the current through the ESD
diodes remains within their rated value. Since OPAx863A is a bipolar amplifier, the two inputs are protected with
anti-parallel back-to-back diodes between them which limits the maximum input differential voltage to
approximately 1 V. Care must be taken to use gain-setting and feedback resistors large enough to limit the
current through these diodes in fast slewing conditions.

8.4 Device Functional Modes
8.4.1 Power-Down Mode
The OPAx863A includes a power-down mode for low-power standby operation with a quiescent current of 8.5
μA (typical) and high output impedance. Many low-power systems are active for only a small time interval when
the parameters of interest are measured and remain in low-power standby mode for a majority of the time for an
overall small average power consumption. The OPAx863A enables such a low-power operation with quick turn-
on within less than 8 μs. Refer to the Electrical Characteristics tables for power-down pin control thresholds.
The OPAx863A is enabled with the PD pin driven to VS+- 0.5 V or higher. The device powers down if the PD pin
is driven to VS+- 1.5 V or lower with a driver device capable of sinking approximately 1 μA (typical) current from
the PD pin. If level translation is needed to realize the PD pin thresholds for enable or power-down modes of
operation, an external pull-up resistor from PD pin to VS+ driven with an open-collector output should be used.

9 Application and Implementation

器件是否适用于其应用。客户应验证并测试其设计,以确保系统功能。
9.1 Application Information
The OPAx863A devices are classic voltage-feedback amplifiers with each channel having two high-impedance
inputs and a low-impedance output. The combination of specifications with a GBW of 50 MHz, 6.3 nV/√Hz
noise, RRIO capability and high-precision performance consuming only 800 µA quiescent current make it an
ideal choice for use in precision data acquisition, reference buffering with fast settling, high gain and filter
circuits. The overload power limit makes OPAx863A truly low-power in high-gain multi-channel systems limiting
any increase in quiescent current during output overload conditions.
9.2 Typical Applications
9.2.1 Low-Power SAR ADC Driver and Reference Buffer
图 9-1 shows the use of the OPAx863A devices as a SAR ADC input driver driving the ADS7057. Sensors,
which are used for interface with the physical environment, exhibit high output impedance and cannot drive SAR
ADC inputs directly. A wide-GBW amplifier like the OPAx863A devices are needed to charge the switching
capacitors at the SAR ADC input and to settle fast to the required accuracy within the given acquisition time. The
OPAx863A's wide-GBW, high precision performance enables fast settling, high accuracy sensor measurements,
and reference buffering for precision ADCs.

9.2.2 Active Filters
Active filter circuits are used to amplify signals in the passband, attenuate signals in the stopband and also limit
the integrated noise at the amplifier's output. The OPAx863A with its wide bandwidth and high-precision
performance is suitable for designing multi-feedback (MFB) low-pass filter circuits.
9.2.2.1 Design Requirements
This section discusses the design of a MFB low-pass active filter with a cut-off frequency at 2 MHz and the
impact of amplifier's gain-bandwidth (GBW) on filter performance.
9.2.2.2 Detailed Design Procedure
图 9-2 shows the use of OPAx863A in a second-order multi-feedback (MFB) low-pass filter with a cut-off
frequency of 2 MHz. The passive component values are first selected for a cut-off frequency at 1 rad/sec and
later scaled for 2 MHz. The frequency response of the circuit in 图 9-2 is compared for various amplifiers with
different gain-bandwidth products and shown in 图9-3:

表9-1 provides the following benefits of using OPAx863A in an MFB low-pass filter circuit:
• High precision measurements with low offset voltage across operating temperature range for low-frequency
signals in passband
• High linearity due to the larger GBW and loop gain for low-frequency signals in passband
• Higher accuracy of cut-off frequency and its smaller variation over process and temperature
• Small integrated output noise due to low-pass filtering
As 图9-3 shows, the amplifier's gain-bandwidth, like the OPAx863A, should be at least 20x greater than the filter
cut-off frequency for a high-precision and linearity low-pass filter design.

10 Power Supply Recommendations
The OPAx863A devices are intended to operate on supplies ranging from 2.7 V to 12.6 V. The OPAx863A
devices may operate on single-sided supplies, split and balanced bipolar supplies, or unbalanced bipolar
supplies. Operating from a single supply can have numerous advantages. The DC errors, due to the –PSRR
term, can be minimized with the negative supply at ground. Typically, AC performance improves slightly at 10-V
operation with minimal increase in supply current. Minimize the distance (< 0.1 in) from the power supply pins to
high-frequency, 0.01-µF decoupling capacitors. A larger capacitor (2.2 µF typical) is used along with a high-
frequency, 0.01-µF supply-decoupling capacitor at the device supply pins. Only the positive supply has these
capacitors for single-supply operation. Use these capacitors from each supply to ground when a split-supply is
used. If necessary, place the larger capacitors further from the device and share these capacitors among several
devices in the same area of the printed circuit board (PCB). An optional supply decoupling capacitor across the
two power supplies (for split-supply operation) reduces second harmonic distortion.
11 Layout
11.1 Layout Guidelines
Achieving optimum performance with a high-frequency amplifier (like the OPAx863A devices) require careful
attention to board layout parasitics and external component types. The High Speed Amplifiers Generic DSN
Evaluation Module user's guide can be used as a reference when designing the circuit board. Recommendations
that optimize performance includes the following:
1. Minimize parasitic capacitance to any AC ground for all of the signal I/O pins. Parasitic capacitance on the
output and inverting input pins can cause instability on the noninverting input and can react with the source
impedance to cause unintentional band-limiting. Open a window around the signal I/O pins in all of the
ground and power planes around those pins to reduce unwanted capacitance. Otherwise, ground and power
planes must be unbroken elsewhere on the board.
2. Minimize the distance (< 0.1 in) from the power-supply pins to high-frequency 0.01-µF decoupling
capacitors. Avoid narrow power and ground traces to minimize inductance between the pins and the
decoupling capacitors. The power-supply connections must always be decoupled with these capacitors.
Larger (2.2-µF to 6.8-µF) decoupling capacitors, effective at lower frequency, must also be used on the
supply pins. These can be placed somewhat farther from the device and shared among several devices in
the same area of the PC board.
3. Careful selection and placement of external components preserve the high frequency performance
of the OPAx863A devices. Resistors must be a low reactance type. Surface-mount resistors work best and
allow a tighter overall layout. Other network components, such as noninverting input termination resistors,
must also be placed close to the package. Keep resistor values as low as possible and consistent with load
driving considerations. Lowering the resistor values keep the resistor noise terms low and minimize the
effect of its parasitic capacitance; lower resistor values, however, increase the dynamic power consumption
because RF and RG become part of the amplifiers output load network.
