7.3.1 Operating Characteristics
The OPAx170-Q1 family of amplifiers is specified for operation from 2.7 V to 36 V (±1.35 V to ±18 V). Many of
the specifications apply from –40°C to +125°C. Parameters that can exhibit significant variance with regard to
operating voltage or temperature are listed in 表 4.

7.3.2 Phase-Reversal Protection
The OPAx170-Q1 family has an internal phase-reversal protection. Many operational amplifiers exhibit a phase
reversal when the input is driven beyond the linear common-mode range. This condition is most often
encountered in noninverting circuits when the input is driven beyond the specified common-mode voltage range,
causing the output to reverse into the opposite rail. The input of the OPAx170-Q1 prevents phase reversal with
excessive common-mode voltage. Instead, the output limits into the appropriate rail. 图 37 shows this
performance.

7.3.3 Electrical Overstress
Designers typically ask questions about the capability of an operational amplifier to withstand electrical
overstress. These questions typically focus on the device inputs, but may involve the supply voltage pins or the
output pin. Each of these different pin functions have electrical stress limits determined by the voltage breakdown
characteristics of the particular semiconductor fabrication process and specific circuits connected to the pin.
Internal electrostatic discharge (ESD) protection is built into these circuits to protect them from accidental ESD
events both before and during product assembly.
A good understanding of basic ESD circuitry and the relevance of the circuitry to an electrical overstress event is
helpful. 图 38 shows the ESD circuits (indicated by the dashed line area) in the OPAx170-Q1. The ESD
protection circuitry involves several current-steering diodes connected from the input and output pins and routed
back to the internal power-supply lines, where the diodes meet at an absorption device internal to the operational
amplifier. This protection circuitry is intended to remain inactive during normal circuit operation.

图 38. Equivalent Internal ESD Circuitry Relative to a Typical Circuit Application
An ESD event produces a short-duration, high-voltage pulse that is transformed into a short-duration, high-
current pulse when discharging through a semiconductor device. The ESD protection circuits are designed to
provide a current path around the operational amplifier core to prevent damage. The energy absorbed by the
protection circuitry is then dissipated as heat.
When an ESD voltage develops across two or more amplifier device pins, current flows through one or more
steering diodes. The absorption device can activate depending on the path of the current. The absorption device
has a trigger (or threshold voltage) that is above the normal operating voltage of the OPAx170-Q1, but below the
device breakdown voltage level. When this threshold is exceeded, the absorption device quickly activates and
clamps the voltage across the supply rails to a safe level.
When the operational amplifier connects into a circuit (see 图 38), the ESD protection components are intended
to remain inactive and do not become involved in the application circuit operation. However, circumstances may
arise where an applied voltage exceeds the operating voltage range of a given pin. If this condition occurs, there
is a risk that some internal ESD protection circuits can turn on and conduct current. Any such current flow occurs
through steering-diode paths and rarely involves the absorption device.
图 38 shows a specific example where the input voltage (VIN) exceeds the positive supply voltage (V+) by 500
mV or more. Much of what happens in the circuit depends on the supply characteristics. If V+ can sink the
current, one of the upper input steering diodes conducts and directs current to V+. Excessively high current
levels can flow with increasingly higher VIN. As a result, the data sheet specifications recommend that
applications limit the input current to 10 mA.
If the supply is not capable of sinking the current, VIN can begin sourcing current to the operational amplifier and
then take over as the source of positive supply voltage. The danger in this case is that the voltage can rise to
levels that exceed the operational amplifier absolute maximum ratings.

Feature Description (接下页)
Another common question involves what happens to the amplifier if an input signal is applied to the input when
the power supplies (V+ or V–) are at 0 V. Again, this question depends on the supply characteristic when at 0 V,
or at a level below the input signal amplitude. If the supplies appear as high impedance, then the input source
supplies the operational amplifier current through the current-steering diodes. This state is not a normal bias
condition; most likely, the amplifier does not operate normally. If the supplies are low impedance, then the current
through the steering diodes can become quite high. The current level depends on the ability of the input source
to deliver current, and any resistance in the input path.
If there is any uncertainty about the ability of the supply to absorb this current, add external Zener diodes to the
supply pins; see 图 38. Select the Zener voltage so that the diode does not turn on during normal operation.
However, the Zener voltage must be low enough so that the Zener diode conducts if the supply pin begins to rise
above the safe-operating, supply-voltage level.
The OPAx170-Q1 input pins are protected from excessive differential voltage with back-to-back diodes, as shown
in 图 38. In most circuit applications, the input protection circuitry has no effect. However, in low-gain or G = 1
circuits, fast-ramping input signals can forward-bias these diodes because the output of the amplifier cannot
respond rapidly enough to the input ramp. If the input signal is fast enough to create this forward-bias condition,
limit the input signal current to 10 mA or less. If the input signal current is not inherently limited, an input series
resistor can limit the input signal current. This input series resistor degrades the low-noise performance of the
OPAx170-Q1. 图 38 is an example configuration that implements a current-limiting feedback resistor.
7.3.4 Capacitive Load and Stability
The dynamic characteristics of the OPAx170-Q1 are optimized for common operating conditions. The
combination of low closed-loop gain and high capacitive loads decreases the phase margin of the amplifier and
can lead to gain peaking or oscillations. As a result, heavier capacitive loads must be isolated from the output.
The simplest way to achieve this isolation is to add a small resistor (for example, ROUT equal to 50 Ω) in series
with the output. 图 39 and 图 40 are graphs showing small-signal overshoot versus capacitive load for several
values of ROUT. See Feedback Plots Define Op Amp AC Performance for details of analysis techniques and
application circuits.

7.4 Device Functional Modes
7.4.1 Common-Mode Voltage Range
The input common-mode voltage range of the OPAx170-Q1 series extends 100 mV below the negative rail and
within 2 V of the top rail for normal operation.
This device can operate with full rail-to-rail input 100 mV beyond the top rail, but with reduced performance within
2 V of the top rail. The typical performance in this range is summarized in 表 5.

7.4.2 Overload Recovery
Overload recovery is defined as the time required for the operational amplifier output to recover from the
saturated state to the linear state. The output devices of the operational amplifier enter the saturation region
when the output voltage exceeds the rated operating voltage, either resulting from the high input voltage or the
high gain. After the device enters the saturation region, the charge carriers in the output devices need time to
return back to the normal state. After the charge carriers return back to the equilibrium state, the device begins to
slew at the normal slew rate. Thus, the propagation delay in case of an overload condition is the sum of the
overload recovery time and the slew time. The overload recovery time for the OPAx170-Q1 is approximately 2
µs.

8 Application and Implementation
注
Information in the following applications sections is not part of the TI component
specification, and TI does not warrant its accuracy or completeness. TI’s customers are
responsible for determining suitability of components for their purposes. Customers should
validate and test their design implementation to confirm system functionality.
8.1 Application Information
The OPAx170-Q1 family of operational amplifiers provides high overall performance in a large number of
general-purpose applications. As with all amplifiers, applications with noisy or high-impedance power supplies
require decoupling capacitors placed close to the device pins. In most cases, capacitors with a value of 0.1 µF
are adequate. Follow the additional recommendations in the Layout Guidelines section to achieve the maximum
performance from this device. Many applications may introduce capacitive loading to the output of the amplifier
that may cause instability. Adding an isolation resistor between the amplifier output and the capacitive load
stabilizes the amplifier. The design process for selecting this resistor is shown in the Typical Application section.
8.2 Typical Application
This circuit can drive capacitive loads such as cable shields, reference buffers, MOSFET gates, and diodes. The
circuit uses an isolation resistor (RISO) to stabilize the output of an operational amplifier. RISO modifies the open-
loop gain of the system to ensure the circuit has sufficient phase margin.

8.2.1 Design Requirements
The design requirements are:
•
•
•
Supply voltage: 30 V (±15 V)
Capacitive loads: 100-pF, 1000-pF, 0.01-μF, 0.1-μF, and 1-μF
Phase margin: 45° and 60°
8.2.2 Detailed Design Procedure
图 41 shows a unity-gain buffer driving a capacitive load. 公式 1 shows the transfer function for the circuit in 图
41. Not shown in 图 41 is the open-loop output resistance of the operational amplifier, RO.

(1)
The transfer function in 公式 1 has a pole and a zero. The frequency of the pole (fp) is determined by (RO + RISO
)
and CLOAD. RISO and CLOAD determine the frequency of the zero (fz). A stable system is obtained by selecting
RISO, so the rate of closure (ROC) between the open-loop gain (AOL) and 1/β is 20 dB / decade. 图 42 depicts the
concept. The 1/β curve for a unity-gain buffer is 0 dB.

the accurate modeling of R
. In addition to simulating the ROC, a robust stability analysis includes a
O
measurement of overshoot percentage and ac gain peaking of the circuit using a function generator,
oscilloscope, and gain and phase analyzer. Phase margin is then calculated from these measurements. 表 6
shows the overshoot percentage and ac gain peaking that correspond to 45° and 60° phase margins. For more
details on this design and other alternative devices that can be used in place of the OPAx170-Q1 family, see
Capacitive Load Drive Solution Using an Isolation Resistor.

9 Power Supply Recommendations
The OPAx170-Q1 family is specified for operation from 2.7 V to 36 V (±1.35 V to ±18 V); many specifications
apply from –40°C to +125°C. Parameters that can exhibit significant variance with regard to operating voltage or
temperature are presented in 表 4.
CAUTION
Supply voltages larger than 40 V can permanently damage the device; see the
Absolute Maximum Ratings table.
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or high-
impedance power supplies. For more detailed information on bypass capacitor placement, see the Layout
section.
10 Layout
10.1 Layout Guidelines
For best operational performance of the device, use good printed circuit board (PCB) layout practices, including:
•
Noise can propagate into analog circuitry through the power pins of the circuit as a whole and the
operational amplifier itself. Bypass capacitors are used to reduce the coupled noise by providing low-
impedance power sources local to the analog circuitry.
–
Connect low-ESR, 0.1-µF ceramic bypass capacitors between each supply pin and ground, placed as
close as possible to the device. A single bypass capacitor from V+ to ground is applicable for single-
supply applications.
•
•
Separate grounding for analog and digital portions of circuitry is one of the simplest and most-effective
methods of noise suppression. One or more layers on multilayer PCBs are typically devoted to ground
planes. A ground plane helps distribute heat and reduces EMI noise pickup. Take care to physically
separate digital and analog grounds, paying attention to the flow of the ground current.
To reduce parasitic coupling, run the input traces as far away as possible from the supply or output
traces. If these traces cannot be kept separate, crossing the sensitive trace perpendicularly is much
better than in parallel with the noisy trace.
•
•
•
Place the external components as close as possible to the device. As shown in 图 45, keeping RF and RG
close to the inverting input minimizes parasitic capacitance.
Keep the length of input traces as short as possible. Always remember that the input traces are the most
sensitive part of the circuit.
Consider a driven, low-impedance guard ring around the critical traces. A guard ring can significantly
reduce leakage currents from nearby traces that are at different potentials.
