The EVAL-CN0241-SDPZ is an evaluation board described in the circuit from the lab CN-0241, entitled "High-side current sensing with input overvoltage protection". High-side current monitors are likely to encounter overvoltage conditions from transients or when the monitoring circuits are connected, disconnected, or powered down. This circuit uses the overvoltage protected ADA4096-2 OPAMP connected as a difference amplifier to monitor the high-side current. The ADA4096-2 has input overvoltage protection, without phase reversal or latch-up, for voltages of 32V higher than and lower than the supply rails. The circuit is powered by the ADP3336 adjustable low dropout 500mA linear regulator, which can also be used to supply power to other parts of the system, if desired. Its input voltage can range from 5.2V to 12V when set for a 5V output.
- Current sensing circuit can be powered down by removing power to the ADP333
- Featured to difference amplifier gain
