INA597IDGKR

Instrumentation, Op Amps, Buffer Amps Overview

The INA597IDGKR is a precision instrumentation amplifier manufactured by Texas Instruments, featuring a fixed gain of 10 V/V. It operates within a supply voltage range of 4.5 V to 36 V and draws a typical operating current of 1.1 mA per channel. Key electrical specifications include an input offset voltage of 200 µV, a gain-bandwidth product of 800 kHz, and a slew rate of 18 V/µs. The device provides a common-mode rejection ratio (CMRR) of 88 dB and exhibits an input voltage noise density of 18 nV/√Hz. It supports an output current of 65 mA per channel and functions reliably across temperatures from -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Provides high-precision signal amplification with low input offset voltage for accurate measurements.
• Features wide common-mode voltage range capability suitable for various sensing applications.
• Delivers high common-mode rejection ratio to effectively suppress noise in differential signals.

Instrumentation, Op Amps, Buffer Amps Applications

• Industrial process control systems requiring precise sensor signal conditioning
• Medical equipment utilizing low-noise amplification for physiological signals
• High-resolution data acquisition systems demanding stable DC performance

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'R' indicates tape-and-reel packaging configuration when ordering. Confirm that the fixed gain of 10 V/V aligns with system requirements, as external resistors are not adjustable. Ensure compatibility with the specified 4.5 V to 36 V supply range and check thermal management needs for the VSSOP-8 package under maximum load conditions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed gain of 10 V/V is required without external resistor trimming. It is suitable for applications needing a balance between precision (low offset) and speed (800 kHz bandwidth). Consider alternatives if variable gain or lower power consumption is critical, as this device prioritizes accuracy over ultra-low power operation.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the INA59x family of precision instrumentation amplifiers from Texas Instruments. The family is designed for applications requiring high accuracy and stability. The IDGKR suffix denotes the VSSOP-8 surface-mount package with reel packaging, distinguishing it from through-hole or tube-packaged variants within the same functional series.
