This small module is a photodiode amplifier. The circuit consists of an OPAMP configured as a transimpedance amplifier for amplifying the light-dependent current of the photodiode. A small bias voltage is derived from the positive supply and applied to the op amp’s non-inverting input. This prevents the output from saturating at the negative supply rail […]

0-1A Single-Supply, Low-Side, Current Sensor with Output 0 to 4.9V

This single-supply, low-side, current sensing solution accurately detects load current between 0 and 1A. The current sensor measures 0 to 1A across the shunt resistor, providing 0 to 4.9V output. The OPA320 features wide bandwidth and low offset voltage making it an excellent amplifier for this design. With a single 5V supply, the LM7705 negative […]
