The OPA381AIDGKR from Texas Instruments is a precision transimpedance amplifier designed for high-speed applications. It provides an 18MHz gain bandwidth (GBW) with excellent long-term stability and very low 1/f noise.
Key electrical characteristics include a low offset voltage of 25µV (max), an offset drift of 0.1µV/°C (max), and a bias current of only 3pA. The amplifier operates from a supply voltage range of 2.7V to 5.5V and consumes a quiescent current of 800µA.
This device is housed in a VSSOP (DGK) 8-pin package and is suitable for precision I/V conversion, photodiode monitoring, optical amplifiers, and CAT-scanner front-ends. It offers a dynamic range of 5 decades and fast overload recovery.
The operating temperature range is -40°C to 125°C. The OPA381 family exceeds the performance of conventional JFET op amps in terms of offset, drift, and noise.
