Overview
The INA122UA/2K5G4 is a single-channel instrumentation amplifier from Texas Instruments, designed for micro-power applications. It operates on a single supply voltage ranging from 2.2 V to 36 V. Key electrical specifications include a 3 dB bandwidth of 120 kHz and a slew rate of 160 mV/us. The device features an input bias current of 25 nA, an input offset voltage of 500 uV, and a common-mode rejection ratio (CMRR) of 83 dB. It consumes 60 uA of operating supply current and functions within a temperature range of -40 C to +85 C.
Feature Summary
- Single-supply operation capability
- Micro-power consumption design
- High common-mode rejection ratio
Applications
- Battery-powered sensor interfaces
- Medical instrumentation
- Industrial process control
Procurement Notes
Verify the specific suffix 'G4' against the manufacturer's latest documentation to confirm RoHS compliance status and any minor specification deviations compared to the standard INA122UA variant. Ensure the SOIC-8 package dimensions match your PCB footprint requirements before finalizing procurement orders.
Selection Notes
Select this component when low power consumption is critical alongside moderate precision requirements. The single-supply architecture simplifies power management in portable devices. Compare the 120 kHz bandwidth against higher-speed alternatives if signal frequency demands exceed this limit.
Part Context
This part belongs to the INA122 family of instrumentation amplifiers, which are known for their ease of use with only one external resistor required to set gain. The UA/2K5 designation indicates surface-mount packaging in a tape-and-reel format, suitable for automated assembly processes.
