Overview
The INA2132U/2K5 is a dual low-power single-supply differential amplifier manufactured by Texas Instruments. It features a wide common-mode input voltage range extending to the negative supply rail and includes an internal precision gain of 10 V/V. The device operates from a single power supply ranging from 2.7 V to 36 V, with a maximum quiescent current of 400 µA per channel. It provides high common-mode rejection ratio (CMRR) and is housed in an 8-pin SOIC package.
Feature Summary
- Dual-channel architecture designed for single-supply operation
- Internal fixed gain of 10 V/V eliminates external resistor requirements
- Wide common-mode input voltage range including the negative rail
- Low power consumption suitable for battery-operated applications
Applications
- Current sensing in single-supply systems
- Signal conditioning for bridge sensors
- Isolated amplifier circuits
- Data acquisition front-ends
Procurement Notes
Verify the specific suffix /2K5 indicates tape-and-reel packaging when ordering. Confirm the manufacturer part number matches exactly to ensure correct component specifications. Check datasheet revisions for any updates to electrical characteristics or mechanical dimensions prior to final design approval.
Selection Notes
Select this component when a fixed gain of 10 is required for differential signal amplification. It is suitable for applications needing wide common-mode voltage handling without external biasing networks. Consider the package size and pin count relative to available board space and routing constraints.
Part Context
This part belongs to the INA213x family of differential amplifiers. It shares functional similarities with other devices in the series but offers specific performance trade-offs regarding power consumption and bandwidth. The U variant denotes the SOIC package option within the product line.
Replacement Considerations
Direct substitutes include other Texas Instruments differential amplifiers with similar gain and package configurations. Verify compatibility regarding input offset voltage, bandwidth, and supply voltage ranges before substitution.
