INA101KU/1K

Overview

The INA101KU/1K is a precision instrumentation amplifier from Texas Instruments, part of the INA101 series. It features a fixed gain of 1 V/V and is housed in a 14-lead CDIP package. Key electrical specifications include a maximum supply voltage of 40 V, an operating temperature range from -55°C to +125°C, and a typical input bias current of 30 nA. The device offers a common-mode rejection ratio (CMRR) of 106 dB and a 3-dB bandwidth of 25 kHz.

Feature Summary

• Provides high accuracy signal amplification with a fixed unity gain configuration
• Features low input bias current for minimal loading on high-impedance sources
• Delivers high common-mode rejection ratio for effective noise suppression

Applications

• Precision data acquisition systems
• Industrial process control instrumentation
• Medical equipment signal conditioning
