Light detecting and ranging (LiDAR), avalanche photodiode
(APD), single photon avalanche diode (SPAD) biasing 5kΩ +105V ADHV4702-1
VOUT –105V –5V Figure 1. The ADHV4702-1 also has a 2 μV/°C maximum input offset
voltage (VOS) drift and an 8 nV/√Hz input voltage noise.
The exceptional dc precision of the ADHV4702-1 is
complemented by excellent dynamic performance with a small
signal bandwidth of 10 MHz and a slew rate of 74 V/μs. The
ADHV4702-1 has an output current of 20 mA typical.
The ADHV4702-1 offers high voltage input common-mode
swing as well as high voltage output swing, enabling precision
high voltage use cases such as high-side current sensing. The
ADHV4702-1 is also ideally suited for forcing a voltage in
precision bias and control applications.
The ADHV4702-1 is available in a 12-lead, 7 mm × 7 mm lead …
