Overview
The OPA859-Q1 is a wideband, low-noise operational amplifier produced by Texas Instruments. It is designed with CMOS inputs for wideband transimpedance and voltage amplifier applications. This amplifier is particularly suited for configurations as a transimpedance amplifier (TIA), enabling high closed-loop bandwidths in low-capacitance photodiode applications. The OPA859-Q1 is optimized for use in optical time-of-flight (ToF) systems, high-speed data acquisition systems, and applications requiring low-noise and high-gain front ends.
