Overview
The INA114AU/1K is a single-channel instrumentation amplifier manufactured by Texas Instruments, housed in an 8-pin SOIC surface-mount package. It operates on a supply voltage range of 2.25V to 18V with a typical quiescent current of 2.2mA. Key electrical specifications include a gain bandwidth product of 1MHz, a slew rate of 60mV/µs, and a maximum input offset voltage of 125µV. The device provides a minimum common-mode rejection ratio (CMRR) of 110dB and features high input impedance of 10GΩ. It supports operation across an extended temperature range from -40°C to +85°C.
Feature Summary
- High common-mode rejection ratio for accurate differential signal amplification
- Low input bias current suitable for high-impedance sensor interfaces
- Wide single or dual power supply operational capability
Applications
- Precision data acquisition systems
- Medical equipment signal conditioning
- Industrial process control instrumentation
Procurement Notes
Verify the specific suffix 'U/1K' against official Texas Instruments documentation to confirm the SOIC-8 package type and reel quantity packaging details. Ensure compatibility with required operating temperatures and supply voltages before integration into final designs.
Selection Notes
Select this component when high CMRR and low input bias current are critical for maintaining signal integrity in precision measurement applications. Consider the SOIC-8 package constraints for PCB layout and thermal management requirements within the specified operating temperature range.
Part Context
This part belongs to the INA114 family of instrumentation amplifiers, designed for general-purpose precision applications. The 'U' designation indicates the SOIC surface-mount package variant, while '/1K' typically denotes tape-and-reel packaging quantities for automated assembly processes.
