INA2132UA

Overview

The INA2132UA is a dual, low-power, single-supply instrumentation amplifier manufactured by Texas Instruments. It features a fixed gain of 5 V/V and operates within a supply voltage range of 2.7 V to 36 V. The device offers high common-mode rejection ratio (CMRR) and low input bias current, making it suitable for precision signal conditioning applications.

Feature Summary

• Dual channel configuration with fixed gain of 5 V/V
• Low power consumption optimized for single-supply operation
• High common-mode rejection ratio for accurate differential measurements

Applications

• Industrial process control sensor interfaces
• Medical equipment signal conditioning
• Data acquisition systems

Procurement Notes

Verify the specific suffix 'UA' corresponds to the SOIC-8 tube package variant when ordering. Confirm that the fixed gain of 5 V/V meets the system requirements, as external resistors cannot adjust this value. Ensure supply voltage limits are respected during integration.

Selection Notes

Select the INA2132UA when a dual-channel solution with fixed gain is required. Compare against the INA2133 or INA2134 if different gain values are needed. Consider the OPA2132 if higher speed or operational amplifier functionality is preferred over instrumentation amplification.

Part Context

This component belongs to the INA213x family of instrumentation amplifiers from Texas Instruments. It shares architectural similarities with other devices in the series but is distinguished by its specific gain setting and dual-channel layout. It complements the company's broader portfolio of precision analog signal chain products.

Replacement Considerations

Check for direct pin-compatible alternatives within the INA213x series such as INA2133UA or INA2134UA if gain adjustments are necessary. Verify electrical specifications match before substituting with general-purpose op-amps like the OPA2132.
