INA592IDT

Instrumentation, Op Amps, Buffer Amps Overview

The INA592IDT is a high-precision, wide-bandwidth e-trim difference amplifier from Texas Instruments. It integrates a precision operational amplifier and a matched resistor network to provide gain configurations of G = 1/2 or G = 2. Key electrical specifications include a maximum input offset voltage of 40 μV, a low offset voltage drift of ±2 μV/°C, and a noise density of 18 nV/√Hz at 1 kHz for the G = 1/2 configuration. The device features a 2 MHz gain-bandwidth product, a slew rate of 18 V/μs, and supports a wide supply range of 4.5 V to 36 V (single) or ±2.25 V to ±18 V (dual). It operates within a temperature range of –40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package variant, as the INA592 family includes SOIC-8, VSSOP-8, and VSON-10 options. Confirm that the IDT suffix corresponds to the SOIC-8 package type required for your PCB layout. Ensure compatibility with the specified single or dual supply voltage ranges during design validation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select the INA592 when a fixed gain of 1/2 or 2 is required with high precision and wide bandwidth. It is suitable for applications needing low offset and drift without the complexity of external resistor networks. Consider the G = 1/2 configuration for lower noise and higher bandwidth compared to the G = 2 setting.

Instrumentation, Op Amps, Buffer Amps Part Context

The INA592 belongs to Texas Instruments' e-trim difference amplifier series, designed to replace discrete resistor-based differential amplifier circuits. It simplifies design by integrating precision resistors directly on-chip, offering improved tracking and thermal stability compared to external resistor networks.
