The OPA855-Q1 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 8-GHz gain bandwidth product (GBWP)
enables high closed-loop bandwidths at transimpedance gains of up to tens of
kΩs.
The following graph shows the bandwidth and noise
performance of the OPA855-Q1 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-Q1 package has a feedback pin
(FB) that simplifies the feedback network connection between
the input and the output.
The OPA855-Q1 is optimized to
operate in optical time-of-flight (ToF) systems where the
OPA855-Q1 is used with
time-to-digital converters, such as the TDC7201. Use the OPA855-Q1 to drive a high-speed
analog-to-digital converter (ADC) in high-resolution LIDAR
systems with a differential output amplifier, such as the
THS4541-Q1.
