INA597IDRCR

Instrumentation, Op Amps, Buffer Amps Overview

The INA597IDRCR is a high-precision, wide-bandwidth e-trim difference amplifier manufactured by Texas Instruments. It integrates a precision operational amplifier and resistor network within a 10-pin VSON package. Key electrical specifications include a maximum input offset voltage of 200 µV at G=1/2 and 400 µV at G=2, with a corresponding drift of ±5 µV/°C and ±10 µV/°C respectively. The device offers a gain bandwidth product of 2 MHz (G=1/2) or 0.8 MHz (G=2), a slew rate of 18 V/µs, and a minimum common-mode rejection ratio of 88 dB. It operates on single supplies from 4.5 V to 36 V or dual supplies from ±2.25 V to ±18 V, consuming 1.1 mA quiescent current.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'CR' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the 10-pin VSON package dimensions align with the target PCB footprint and thermal management requirements. Ensure the selected gain configuration matches the application needs, as internal pin connections differ between G=1/2 and G=2 modes.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high accuracy and wide bandwidth are required in a cost-sensitive industrial environment. The integrated resistor network eliminates the need for external precision resistors, simplifying design while maintaining gain accuracy. Consider the 10-pin VSON package for space-constrained layouts requiring a thermal pad for heat dissipation.

Instrumentation, Op Amps, Buffer Amps Part Context

The INA597 belongs to the e-trim family of difference amplifiers, designed to replace discrete resistor networks. Unlike standard instrumentation amplifiers, it provides a fixed gain structure optimized for differential signal conditioning. The IDRCR variant specifically denotes the industrial temperature range and the VSON package type.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the gain configuration affect the input pins?

For G=1/2, +IN and -IN serve as inputs while REF is grounded. For G=2, +INOP and -INOP connect to inputs, REF connects to output, and SENSE connects to the negative input.

What is the maximum capacitive load the device can drive?

The INA597 is specified to drive capacitive loads up to 500 pF directly without oscillation.
