OPA397 Single Low offset, Low Noise RRIO e-trim™ Op-Amp | Datasheet Preview

Texas Instruments’ OPA397 Single Low offset, Low Noise RRIO e-trim™ Op-Amp is cost-optimized and suitable for upstream analog signal chain and downstream signal chain applications. The OPA397 features TI's e-trim op-amp technology to achieve ultra-low offset voltage and offset voltage drift without input chopping or auto-zero techniques. This technique enables ultra-low input bias current for sensor inputs or photodiode current-to-voltage measurements, creating high-performance transimpedance stages for optical modules or medical instrumentation. The OPA397 features ultra-low offset voltage, drift, and supply voltage operation, and a fast slew rate with a high output current as well as rail-to-rail input and output operation. This op-amp offers precision DC accuracy and the AC performance is optimized for low noise and fast-settling transient response. These features make the OPA397 ideal for driving high-precision analog-to-digital converters or buffering the output of high-resolution, digital-to-analog converters.
