Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any Absolute Maximum

Rating condition for extended periods may affect device reliability and lifetime.

Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.

Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power supply, the input

current should be limited to less than 10mA.

Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply voltage and how many

amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The specified values are for short traces

connected to the leads.

Operation

The TP2301 series op amps can operate on a single-supply voltage (2.2 V to 5.5 V), or a split-supply voltage (±1.1 V to

±2.75 V), making them highly versatile and easy to use. The power-supply pins should have local bypass ceramic

capacitors (typically 0.001 μF to 0.1 μF). These amplifiers are fully specified from +2.2 V to +5.5 V and over the

extended temperature range of –40°C to +125°C. Parameters that can exhibit variance with regard to operating voltage

or temperature are presented in the Typical Characteristics

Applications Information

Input ESD Diode Protection

The TP2301 incorporates internal electrostatic discharge (ESD) protection circuits on all pins. In the case of input and

output pins, this protection primarily consists of current-steering diodes connected between the input and power-supply

pins. These ESD protection diodes also provide in-circuit input overdrive protection, as long as the current is limited to

10 mA as stated in the Absolute Maximum Ratings table. Many input signals are inherently current-limited to less than

10 mA; therefore, a limiting resistor is not required. Figure 1 shows how a series input resistor (RS) may be added to

the driven input to limit the input current. The added resistor contributes thermal noise at the amplifier input and the

value should be kept to the minimum in noise-sensitive applications.

PHASE REVERSAL

The TP230x op amps are designed to be immune to phase reversal when the input pins exceed the supply voltages,

therefore providing further in-system stability and predictability. Figure 2 shows the input voltage exceeding the supply

voltage without any phase reversal.

Figure 2. No Phase Reversal

EMI SUSCEPTIBILITY AND INPUT FILTERING

Operational amplifiers vary in susceptibility to electromagnetic interference (EMI). If conducted EMI enters the device,

the dc offset observed at the amplifier output may shift from the nominal value while EMI is present. This shift is a result

of signal rectification associated with the internal semiconductor junctions. While all operational amplifier pin functions

can be affected by EMI, the input pins are likely to be the most susceptible. The TP2301 operational amplifier family

incorporates an internal input low-pass filter that reduces the amplifier response to EMI. Both common-mode and

differential mode filtering are provided by the input filter. The filter is designed for a cutoff frequency of approximately

400 MHz (–3 dB), with a roll-off of 20 dB per decade.

ACTIVE FILTER

The TP230x is well-suited for active filter applications that require a wide bandwidth, fast slew rate, low-noise,

single-supply operational amplifier. Figure 4 shows a 20-kHz, second-order, low-pass filter using the multiplefeedback

(MFB) topology. The components have been selected to provide a maximally-flat Butterworth response. Beyond the

cutoff frequency, roll-off is –40 dB/dec. The Butterworth response is ideal for applications that require predictable gain

characteristics, such as the anti-aliasing filter used in front of an ADC.

One point to observe when considering the MFB filter is that the output is inverted, relative to the input. If this inversion

is not required, or not desired, a noninverting output can be achieved through one of these options:

1. adding an inverting amplifier;

2. adding an additional second-order MFB stage

PCB Surface Leakage

In applications where low input bias current is critical, Printed Circuit Board (PCB) surface leakage effects need to be

considered. Surface leakage is caused by humidity, dust or other contamination on the board. Under low humidity

conditions, a typical resistance between nearby traces is 10¹²Ω. A 5V difference would cause 5pA of current to flow,

which is greater than the TP2301/2302/2304 OPA’s input bias current at +27°C (±3pA, typical). It is recommended to

use multi-layer PCB layout and route the OPA’s -IN and +IN signal under the PCB surface.

The effective way to reduce surface leakage is to use a guard ring around sensitive pins (or traces). The guard ring is

biased at the same voltage as the sensitive pin. An example of this type of layout is shown in Figure 1 for Inverting

Gain application.

1. For Non-Inverting Gain and Unity-Gain Buffer:

a) Connect the non-inverting pin (V_IN+) to the input with a wire that does not touch the PCB surface.

b) Connect the guard ring to the inverting input pin (V_IN–). This biases the guard ring to the Common Mode input voltage.

2. For Inverting Gain and Trans-impedance Gain Amplifiers (convert current to voltage, such as photo detectors):

a) Connect the guard ring to the non-inverting input pin (V_IN+). This biases the guard ring to the same reference voltage as the

op-amp (e.g., V_DD/2 or ground).

b) Connect the inverting pin (V_IN–) to the input with a wire that does not touch the PCB surface.

Power Supply Layout and Bypass

The TP2301/2302/2302 OPA’s power supply pin (V_DDfor single-supply) should have a local bypass capacitor (i.e.,

0.01μF to 0.1μF) within 2mm for good high frequency performance. It can also use a bulk capacitor (i.e., 1μF or larger)

within 100mm to provide large, slow currents. This bulk capacitor can be shared with other analog parts.

Ground layout improves performance by decreasing the amount of stray capacitance and noise at the OPA’s inputs

and outputs. To decrease stray capacitance, minimize PC board lengths and resistor leads, and place external

components as close to the op amps’ pins as possible.

Proper Board Layout

To ensure optimum performance at the PCB level, care must be taken in the design of the board layout. To avoid

leakage currents, the surface of the board should be kept clean and free of moisture. Coating the surface creates a

barrier to moisture accumulation and helps reduce parasitic resistance on the board.

Keeping supply traces short and properly bypassing the power supplies minimizes power supply disturbances due to

output current variation, such as when driving an ac signal into a heavy load. Bypass capacitors should be connected

as closely as possible to the device supply pins. Stray capacitances are a concern at the outputs and the inputs of the

amplifier. It is recommended that signal traces be kept at least 5mm from supply lines to minimize coupling.

A variation in temperature across the PCB can cause a mismatch in the Seebeck voltages at solder joints and other

points where dissimilar metals are in contact, resulting in thermal voltage errors. To minimize these thermocouple

effects, orient resistors so heat sources warm both ends equally. Input signal paths should contain matching numbers

and types of components, where possible to match the number and type of thermocouple junctions. For example,

dummy components such as zero value resistors can be used to match real resistors in the opposite input path.

Matching components should be located in close proximity and should be oriented in the same manner. Ensure leads

are of equal length so that thermal conduction is in equilibrium. Keep heat sources on the PCB as far away from

amplifier input circuitry as is practical.

The use of a ground plane is highly recommended. A ground plane reduces EMI noise and also helps to maintain a

constant temperature across the circuit board.
