Description
General part information
OPA856 Series
The OPA856 is a wideband, low-noise operational amplifier with bipolar inputs for wideband transimpedance and voltage amplifier applications. When the device is configured as a transimpedance amplifier (TIA), the 1.1-GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths in low-capacitance photodiode applications.
The graph below shows the bandwidth and noise performance of the OPA856 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 OPA856 package has a feedback pin (FB) that simplifies the feedback network connection between the input and the output.
The OPA856 is optimized to operate in optical time-of-flight (ToF) systems where the OPA856 is used with time-to-digital converters, such as theTDC7201. Use the OPA856 to drive a high-speed analog-to-digital converter (ADC) in high-resolution LIDAR systems with a differential output amplifier, such as theTHS4541orLMH5401.
