The OPA2381AIDGKR from Texas Instruments is a high-precision, low-power transimpedance amplifier designed for demanding I/V conversion applications. It features an impressive 18MHz gain bandwidth (GBW) and a dynamic range of 5 decades, making it suitable for a wide array of optical and sensing applications.
Key electrical characteristics include a very low bias current of 3pA, a maximum offset voltage of 25µV, and an offset drift of 0.1µV/°C. The amplifier also boasts low voltage noise at 10nV/√Hz and a quiescent current of 800µA. It operates within a supply voltage range of 2.7V to 5.5V.
Packaged in an 8-pin VSSOP (DGK) with surface mount mounting, the OPA2381AIDGKR is designed for precision I/V conversion, photodiode monitoring, optical amplifiers, and CAT-scanner front-ends. Its excellent long-term stability and fast overload recovery contribute to its reliability in sensitive measurement systems.
