INA114BP

Overview

The INA114BP is a precision instrumentation amplifier manufactured by Texas Instruments, housed in an 8-pin PDIP package. It operates on dual power supplies ranging from ±2.5 V to ±15 V or single supplies up to 30 V. The device features a low input offset voltage of 125 µV and a high common-mode rejection ratio (CMRR) of 110 dB. With a gain bandwidth product of 1 MHz and a slew rate of 60 mV/µs, it supports precise signal conditioning for low-frequency applications.

Feature Summary

• High common-mode rejection ratio ensures accurate differential signal amplification
• Low input offset voltage maintains precision in sensitive measurement circuits
• Flexible supply voltage operation supports diverse system architectures

Applications

• Strain gauge and load cell interfaces
• Medical equipment signal conditioning
• Industrial process control sensors

Procurement Notes

Verify the specific suffix 'BP' against official Texas Instruments documentation to confirm pinout and package dimensions. Ensure compatibility with required operating temperature ranges and supply voltages before integration into final designs.

Selection Notes

Select this component when high CMRR and low offset voltage are critical. Compare against other instrumentation amplifiers based on bandwidth requirements and supply voltage constraints. Verify that the PDIP-8 package fits the target PCB layout.

Part Context

The INA114 series belongs to Texas Instruments' family of precision instrumentation amplifiers. These devices are designed for applications requiring high accuracy and stability. The BP variant specifically denotes the plastic DIP package configuration, distinguishing it from surface-mount alternatives within the same functional family.

Replacement Considerations

Check datasheets for equivalent models such as INA114AP or INA114BU. Confirm pin compatibility and electrical specifications match the original design requirements before substitution.
