Overview
The INA117KU is a high common-mode voltage difference amplifier manufactured by Texas Instruments. It operates on dual power supplies ranging from 10 V to 36 V with a typical supply current of 1.5 mA. The device features a single channel in an SOIC-8 surface-mount package, supporting operation temperatures from -40°C to +85°C. Key electrical specifications include a slew rate of 2.6 V/µs, a 3dB bandwidth of 200 kHz, and a minimum common-mode rejection ratio (CMRR) of 66 dB. Input offset voltage is specified at a maximum of 2 mV.
Feature Summary
- Supports high common-mode voltages for differential signal processing
- Provides precision amplification with low input offset voltage
- Features high common-mode rejection ratio for noise immunity
Applications
- Industrial process control systems
- Medical equipment signal conditioning
- Data acquisition systems
Procurement Notes
Verify the specific suffix 'KU' against the manufacturer's official datasheet to confirm the exact package type and tape-and-reel configuration. Ensure the ordering part number matches the required RoHS compliance status and temperature grade. Cross-reference the manufacturer's latest documentation to confirm availability and any potential design changes or obsolescence notices before finalizing procurement.
Selection Notes
Select this component when high common-mode voltage handling is required alongside precise differential amplification. Compare the 66 dB CMRR and 2.6 V/µs slew rate against application requirements. Consider the SOIC-8 package for surface-mount assembly constraints. Evaluate alternative packages like DIP or TO-99 if through-hole mounting is necessary for the same circuit topology.
Part Context
The INA117 belongs to a family of difference amplifiers designed for applications requiring high common-mode voltage rejection. Unlike instrumentation amplifiers that offer adjustable gain, this device typically provides a fixed gain of 1 V/V. It serves as a robust solution for isolating small differential signals from large common-mode potentials in noisy environments.
Replacement Considerations
INA117P: Through-hole DIP variant with identical electrical characteristics. INA117BM: Metal can package version offering potentially higher performance metrics.
