The OPA855 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 8GHz gain bandwidth product (GBWP) enables high
closed-loop bandwidths at transimpedance
gains of up to tens of kilohms.
The following graph shows the bandwidth and noise
performance of the OPA855 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 OPA855 package has a feedback pin
(FB) that simplifies the feedback network connection between
the input and the output.
The OPA855 is optimized to
operate in optical time-of-flight (ToF) systems where the OPA855 is used
with time-to-digital converters, such as the TDC7201. Use the OPA855 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.
