INA163UAE4

Overview

The INA163UAE4 is a monolithic instrumentation amplifier manufactured by Texas Instruments, housed in a 14-SOIC package. It features current-feedback circuitry designed for very wide bandwidth and low distortion. Key electrical specifications include a slew rate of 15 V/µs, a -3dB bandwidth of 800kHz, an input bias current of 2µA, and a common-mode rejection ratio (CMRR) of 100 dB. The device operates within a supply voltage range of ±4.5V to ±18V and supports a maximum operating temperature of +85°C.

Feature Summary

• Monolithic instrumentation amplifier architecture
• Current-feedback circuitry for wide bandwidth
• Low-noise and low-distortion performance

Applications

• Precision signal conditioning
• Data acquisition systems
• Medical instrumentation

Procurement Notes

This component is classified as End of Life and scheduled for obsolescence by the manufacturer. Verification of availability should focus on surplus or secondary market sources rather than direct new production from Texas Instruments. Ensure authenticity checks are performed when sourcing from distributors due to discontinued status.

Selection Notes

Engineers requiring this specific part must account for its obsolete lifecycle status. Selection should consider the trade-off between the device's high-speed current-feedback characteristics and the long-term supply chain risks associated with discontinuation. Alternative components with similar bandwidth and noise profiles should be evaluated for new designs.

Part Context

The INA163 series represents Texas Instruments' approach to high-speed instrumentation amplification using current-feedback topology. The UAE4 suffix denotes the specific tape-and-reel packaging variant of the standard INA163UA device. This family targets applications demanding fast settling times and wide dynamic range in compact surface-mount formats.
