The OPA859 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 0.9GHz gain bandwidth product (GBWP) enables high closed-loop bandwidths in
low-capacitance photodiode applications.
The following graph shows the bandwidth and noise
performance of the OPA859 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 OPA859 package has a feedback pin
(FB) that simplifies the feedback network connection between
the input and the output.
The OPA859 is optimized to
operate in optical time-of-flight (ToF) systems where the OPA859 is used
with time-to-digital converters, such as the TDC7201. Use the OPA859 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.
