3 Description
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 5.5-GHz gain bandwidth product
(GBWP) enables applications requiring high closedloop bandwidths at transimpedance gains in the tens
to hundreds of kΩs range.
The graph below demonstrates 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 over
a bandwidth range extending from DC to the
calculated f-3dB frequency on the left-hand scale. The
OPA858 package features 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-ofFlight (ToF) systems like the one shown in the figure
below where the OPA858 is used with the TDC7201
time-to-digital converter. The OPA858 can be used in
high-resolution LIDAR systems with a high-speed
analog-to-digital converter (ADC) and a differential
output amplifier like the THS4541 or LMH5401 to
drive the ADC.
