Description

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.

Features
  •  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
