Micropower Electrochemical Gas Sensor Amplifier Reference Design

1 января 2018

This reference design consists of a micropower “Potentistat” type electrochemical sensor circuit for battery operated portable or long-life portable or fixed remote location devices. Using a nanopower amplifier and reference circuit allows the circuit to function continuously and independently of the monitoring processor to keep the sensor biased to avoid lengthy start-up settling times.

Особенности

Potentiometric type amplifier adaptable for many electrochemical cell applications Accommodates biased and unbiased sensors Adaptable to many two and three terminal electrochemical cell applications Micropower (<1uA) total amplifier circuit supply current for long battery life Booster-Pack compatible PCB format for use with MSP430 LaunchPad development platform
