The OPA858 is a wideband, low-noise operational amplifier with CMOS inputs for wideband transimpedance and voltage amplifier applications. When the device is configured as a transimpedance amplifier (TIA), the 5.5GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths at transimpedance gains in the range of tens to hundreds of kilohms. The following graph shows the bandwidth and noise performance of the OPA858 as a function of the photodiode capacitance when the amplifier is configured as a TIA. The total noise is calculated along a bandwidth range extending from dc to the calculated frequency (f) on the left scale. The OPA858 package has a feedback pin (FB) that simplifies the feedback network connection between the input and the output. The OPA858 is optimized to operate in optical time-of-flight (ToF) systems where the OPA858 is used with time-to-digital converters, such as the TDC7201. Use the OPA858 to drive a high-speed analog-to-digital converter (ADC) in high-resolution LIDAR systems with a differential output amplifier, such as the THS4541 or LMH5401 devices.
