INA592IDGKT

Instrumentation, Op Amps, Buffer Amps Overview

The INA592IDGKT is a high-precision, wide-bandwidth difference amplifier from the e-trim series by Texas Instruments. It features a fixed gain of 10 V/V and operates with a supply voltage range of 2.7V to 36V. Key electrical parameters include a maximum input offset voltage of 25µV, a gain bandwidth product of 10MHz, and a slew rate of 4V/µs. The device provides a common-mode rejection ratio (CMRR) of 80dB at DC and maintains high performance across an industrial temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Integrated laser-trimmed resistors ensure high precision without external matching components
• Wide common-mode voltage range supports operation up to 36V independent of supply
• Fixed unity-gain or higher configurations available for simplified circuit design
• High CMRR performance maintained over wide frequency bands

Instrumentation, Op Amps, Buffer Amps Applications

• Industrial process control signal conditioning

• Current sensing applications in power management

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DGKT' corresponds to the tape-and-reel packaging variant when ordering. Confirm that the fixed gain configuration matches the application requirements, as internal resistor networks are not user-adjustable. Ensure the PCB footprint aligns with the VSSOP-8 package dimensions specified in the official mechanical drawings.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a fixed-gain difference amplifier is required to simplify layout and reduce component count. It is suitable for applications needing high common-mode rejection and wide bandwidth. Consider alternative models if variable gain or lower cost is prioritized over precision. Verify that the input common-mode voltage range covers the expected signal levels.

Instrumentation, Op Amps, Buffer Amps Part Context

The INA592 belongs to Texas Instruments' e-trim family of difference amplifiers, which utilize laser trimming to achieve high accuracy. This series is designed to replace discrete resistor networks, offering improved stability and reduced board space. The IDGKT designation indicates a specific thermal and packaging variant within the broader INA592 product line.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct pin-to-pin replacements may include other e-trim difference amplifiers from the same manufacturer. Verify gain accuracy and bandwidth specifications against the original design requirements before substitution.
