TP2331/TP2332 /TP2334

1.6MHz Bandwidth, Low Noise Precision Op‐amps

Description

Features

The TP2331/TP2332/TP2334 are single/dual/quad, low

offset, low noise operational amplifiers with low power

consumption and rail-to-rail input/output swing.



Offset Voltage: 50 μV (max)

Low Noise: 13nV/√Hz(f= 1kHz)

Supply Current: 190μA/ch

Input offset voltage is trimmed to less than 50μV and the

CMOS inputs draw less than 0.3pA of bias current. The

low offset drift, excellent CMRR, and high voltage gain

make it a good choice for precision signal conditioning.

Low THD+N: 0.0005%

Supply Range: 2.2V to 5.5V

Low Input Bias Current: 0.3pA Typical

Slew Rate: 0.9 V/μs

Each amplifier draws only 190μA current on a 3V supply.

The micro power, rail-to-rail operation of the TP233x

series is well suited for portable instruments and single

supply applications.

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 TP2331/TP2332/TP2334 can operate from a single +2.2V to +5.5V power supply, or from ±1.1V to ±2.75V power

supplies. The power supply pin(s) must be bypassed to ground with a 0.1μF capacitor as close to the pin as possible.

This series are high-precision op amps with a CMOS input stage and an excellent set of DC and AC features. The

combination of tight maximum voltage offset, low offset tempco and very low input current make them ideal for use in

high-precision DC circuits. They feature low-voltage operation, low-power consumption, high-current drive with

rail-to-rail output swing and high-gain bandwidth product.

Applications Information

High Accuracy

The TP2331/TP2332/TP2334 maximum input offset voltage is 50μV (2μV, typ) at +25°C. The maximum temperature

coefficient of the offset voltage are guaranteed to be 2μV/°C. The parts have an input bias current of 0.3pA. Noise

characteristics are 13nV/√Hz, and a low frequency noise (0.1Hz to 10Hz) of 4.1μVp-p. The CMRR is 140dB, and the PSRR is

120dB. The combination is what is necessary for the design of circuits to process signals while keeping high signal-to-noise

ratios, as in stages preceding high-resolution converters, or when they are produced by sensors or transducers generating

very small outputs.

Rail-to-Rail Inputs and Outputs

The TP233x 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 1 shows the input voltage exceeding the supply

voltage without any phase reversal.

Input ESD Diode Protection

The TP2331 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 2 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.

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 TP2331 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.

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 TP2331/2332/2334 OPA’s input bias current at +27°C (±0.3pA, 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 6 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.

Figure 6 The Layout of Guard Ring

Power Supply Layout and Bypass

The TP2331/2332/2332 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.
