Low-noise interface IC suits capacitive sensors

Low-noise interface IC suits capacitive sensors

The CPIC2.0 capacitive sensor interface platform can measure transducers with a base capacitance from 1 to 32 pF. It has a low-noise level of 30 aF (1aF = 10-18 F), and contains a dual-capacitor input enabling several configurations, including ΔCsens / ∑Csens.

In addition, it embeds a temperature sensor and an EEPROM for storage of calibration parameters, temperature, and pressure compensation and has an easy-to-use microcontroller interface (SPI/TWI). The design can be used for “static” and “dynamic” applications, which require from fewer than 1 up to 166 samples/s. (Call Sylvie Mattei for pricing — available now.)
