INA2137PA

Overview

The INA2137PA is a dual-channel differential line receiver manufactured by Texas Instruments. It operates from a single 9V supply or dual supplies ranging from ±2.25V to ±18V, with a maximum total supply voltage of 36V. The device features a 14-pin PDIP package and supports through-hole mounting. Key electrical specifications include a gain bandwidth product of 1 MHz, a slew rate of 3.5 V/µs, and an input bias current of 100 pA. It provides a common-mode rejection ratio of 84 dB and delivers up to 60 mA output current per channel while consuming 220 µA of operating supply current.

Feature Summary

• Dual-channel architecture for simultaneous signal processing
• Rail-to-rail input and output capability
• Low power consumption suitable for battery-operated systems
• High common-mode rejection for noise immunity

Applications

• Differential signal transmission in industrial environments
• Audio line receiving circuits

Procurement Notes

Verify the specific part number against official Texas Instruments documentation to confirm pinout compatibility and electrical ratings. Ensure the procurement source provides valid manufacturer traceability. Check for RoHS compliance status as indicated in the latest datasheet revisions. Confirm that the package type matches the intended PCB footprint requirements before finalizing orders.

Selection Notes

Select this component when dual-channel differential reception is required within a low-power constraint. The rail-to-rail I/O allows operation across wide supply ranges. Consider the 14-pin PDIP package for prototyping or through-hole manufacturing needs. Evaluate the 84 dB CMRR against system noise levels to ensure adequate signal integrity for the specific application environment.

Part Context

The INA2137PA belongs to the MicroAmplifier series, designed for general-purpose operational amplifier applications. It integrates two independent channels within a single package to reduce board space. The device utilizes JFET input technology to achieve low input bias currents. This series targets cost-sensitive designs requiring reliable performance in standard industrial temperature ranges.
