Accurate signal conditioning and high-resolution measurements are no longer limited to industrial or instrumentation applications. Designers of portable consumer- electronic equipment also need to ...
This Circuit can compare the Light level in an area. It uses a PN Photodiode as the light sensor and IC CA3140 as voltage comparator. The circuit is ideal as the front end of burglar alarm circuits.
Melexis has brought out a dual-input inductive sensor integrated circuit (IC). The device simultaneously processes signals from two sets of coils to compute differential or vernier angles on-chip.
