AD5940BCBZ-RL7

The AD5940 is high precision, low power analogue front ends (AFEs) designed for portable applications that require high precision, electrochemical-based measurement techniques such as amperometric, voltammetric, or impedance measurements. The AD5940 is designed for skin impedance and body impedance measurements and works with the AD8233 AFE in a complete bioelectric or biopotential measurement system. The AD5940 is designed for electrochemical toxic gas sensing. Typical applications include electrochemical measurements, electrochemical gas sensors, potentiostat/amperometric/voltammetry/cyclic voltammetry, bioimpedance applications (skin impedance, body impedance), continuous glucose monitoring, battery impedance.
