Leaders of e2v introduce low-noise interface for capacitive sensors

Leaders of e2v Technologies plc in Chelmsford, England, are introducing the CPIC2.0 high-resolution, low-power interface integrated circuit (IC) for capacitive sensors. Experts at e2v have made capacitive measurements, with 30aF resolution and a few micro amps current consumption, as easy as reading registers, company officials say. The company’s Mixed Signal ASIC (MSA) business unit specializes in solutions for sensor data acquisition in applications for safety and security, energy management and pollution reduction, and health and sports. The platform integrated circuits (ICs) from e2v are analog front-ends containing all the interface platforms (IPs) necessary to interface transducers. CPIC2.0 is part of e2v’s platform IC family, dedicated to very low-power, high-resolution measurement of capacitive sensing elements. CPIC2.0 can measure transducers with a base capacitance from 1 to 32 pF. It has a noise level of 30 aF (1aF = 10-18F), and contains a dual capacitor.
