AD5940BCBZ-RL

AD5940 is a high precision, impedance, and electrochemical front end. It 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. It 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. This consist of two high precision excitation loops and one common measurement channel, which enables a wide capability of measurements of the sensor under test. Application includes electrochemical measurements, electrochemical gas sensors, potentiostat/amperometric/voltammetry/cyclic, voltammetry, bioimpedance applications, skin impedance, body impedance, continuous glucose monitoring, battery impedance.
