说明

The MAX30131/MAX30132/MAX30134 are ultra-low power programmable analog front ends (AFE) for use with electrochemical sensors. The devices provide the biasing and complete measurement path, including the analog to digital converters (ADCs). The flexibility of the MAX30131/MAX30132/MAX30134 enables them to work with both two and three terminal electrochemical sensors, providing both DC current measurement and electrochemical impedance spectroscopy (EIS) measurement capability. The devices include an internal temperature sensor and programmable voltage reference but also support external temperature monitoring and an external reference source. The MAX30131/MAX30132/MAX30134 also integrate voltage monitoring of bias and supply voltages for safety and compliance.

The MAX30131/MAX30132/MAX30134 support single-, dual-, and quad- two-terminal or three-terminal electrochemical sensors, respectively. Ultra-low power allows for the continuous biasing of the sensor to maintain accuracy and fast response when a measurement is required. The MAX30131/MAX30132/MAX30134 operate over a 1.7V to 5.0V voltage range. Total current consumption can be less than 5μA depending on the configuration, measurement frequency, and number of sensors. Communication is through a 4-pin SPI serial interface plus a configurable interrupt pin and four configurable general purpose input/outputs (GPIOs) for direct control of internal functions.

The MAX30131/MAX30132/MAX30134 are available in a 25-bump WLP package and operate over a 0°C to +70°C temperature range.
