The Texas Instruments INA128U is a versatile instrumentation amplifier designed for precision measurement applications. It boasts a high Common Mode Rejection Ratio (CMRR) of 120dB minimum and a low input offset voltage of 50µV maximum, ensuring accurate signal amplification.
With a bandwidth of 1.3MHz at a gain of 1, the INA128U is suitable for a variety of signal conditioning tasks. It operates from a wide supply voltage range of ±2.25V to ±18V and consumes only 700µA of quiescent current, making it ideal for low-power applications.
The device features robust input protection up to ±40V and is available in SOIC and PDIP packages. Its low noise characteristics (8nV/√Hz at 1kHz) and low input bias current make it well-suited for amplifying small differential signals in the presence of large common-mode voltages.
Key electrical specifications include a maximum gain error of 0.5% and a low input offset drift of 0.5µV/°C. The INA128U is designed for operation across a temperature range of -40°C to 125°C.
