1. This circuit, based on a PIC microcontroller with a few added components, converts a sensor-based voltage into a 4- to 20-mA current loop. Shown is the circuit as originally drawn on a whiteboard.

1. Typical application circuit: The device outputs an analog signal (VOUT) that varies linearly with the bidirectional AC or DC primary current, IP, within the ranges specified.

A sensor signal conditioner (SSC) is an integrated circuit that improves — or conditions — the signal coming from a sensor to reduce noise. The SSC also converts the signal from analog to digital ...
