Texas Instruments OPA858/OPA858-Q1 Wideband Op Amps
Texas Instruments OPA858/OPA858-Q1 Wideband Operational Amplifiers with CMOS inputs are an ideal solution for wideband transimpedance and voltage amplifier applications. Applications requiring high closed-loop bandwidths at transimpedance gains in the tens to hundreds of kΩs range are enabled when the device is configured as a transimpedance amplifier (TIA). An additional feature on the device is a feedback pin (FB) that simplifies the feedback network connection between the input and the output. The OPA858 is optimized for use in optical Time-of-Flight (ToF) systems. When combined with a high-speed analog-to-digital converter (ADC), the OPA858/OPA858-Q1 can be employed in high-resolution LIDAR systems using a differential output amplifier to drive the ADC. The OPA858-Q1 devices are AEC-Q100 qualified for automotive applications.Features
