Overview
The INA132UA/2K5 is a low-power, single-supply difference amplifier manufactured by Texas Instruments. It features a fixed gain of 1 V/V and operates within a supply voltage range of 2.7V to 36V (single) or ±1.35V to ±18V (dual). Key electrical parameters include a gain bandwidth product of 300 kHz, a slew rate of 0.1 V/us, and a common-mode rejection ratio of 70 dB. The input offset voltage is 75 uV, with an operating supply current of 160 uA. It supports an output current of 12 mA per channel and functions in temperatures from -40°C to +85°C.
Feature Summary
- Integrates precision resistor networks laser-trimmed for accurate gain and high common-mode rejection.
- Operates on a single power supply with input common-mode range extending to the negative rail.
- Resistor temperature coefficient tracking maintains gain accuracy and CMRR across temperature variations.
Applications
- Current sensing circuits
- Isolated amplifiers
- Voltage level shifting
Procurement Notes
Verify the specific suffix /2K5 indicates reel packaging when ordering. Confirm the SOIC-8 package type matches your PCB footprint requirements. Ensure the extended industrial temperature range (-40°C to +85°C) meets your environmental specifications. Check moisture sensitivity levels for proper storage and handling procedures during assembly.
Selection Notes
Select this component for applications requiring a fixed unity-gain differential-to-single-ended conversion without external precision resistors. It is suitable for low-power designs due to its 160 uA supply current. Consider the 300 kHz bandwidth and 0.1 V/us slew rate for signal integrity in moderate-speed applications.
Part Context
This device belongs to the INA132 family of difference amplifiers. It replaces discrete resistor networks that typically require expensive, matched components to achieve similar performance. The integrated design simplifies circuit layout and reduces board space while ensuring consistent performance characteristics across production batches.
