Operational amplifiers are an ideal solution for wideband transimpedance

Texas Instruments OPA858 Wideband Operational Amplifiers with CMOS inputs are an ideal solution for wideband transimpedance and voltage amplifier applications. Applications needing high closed-loop bandwidths at transimpedance gains in the tens to hundreds of kOhms range are activated when the device is configured as a TIA. An added feature on the device is a feedback pin that simplifies the feedback network connection between the input and the output. The device is optimised for use in optical Time-of-Flight systems. When combined with a high-speed ADC, the device can be used in high-resolution LIDAR systems using a differential output amplifier to drive the ADC. Typical applications include laser distance measurement, level transmitter (optical), optical time domain reflectometry, distributed temperature sensing, 3D scanner, and autonomous driving systems.
