Signal Conditioning ASICs

ESS has designed and fabricated a family of full custom mixed-signal ASICs for capacitive sensor signal conditioning.


The ESS capacitive signal conditioning ASICs are capable of interfacing all kinds of capacitive sensors, both of single and differential architecture and they are the ideal signal conditioners for the capacitive pressure sensors and accelerometers designed by ESS.

The core architecture of the ESS capacitive signal conditioning ASICs utilizes noise reduction techniques in order to improve SNR and to provide high resolution digital and analog outputs.

The resulted high performance in combination with the fully programmable configurations and the embedded functionalities makes the ESS capacitive signal conditioning ASIC family able to serve a wide range of capacitive sensor applications.
