MAX40109
Description
The MAX40109 is a low-power, precision sensor interface So C that includes a high-precision, programmable Analog frontend (AFE), Analog-to-Digital Converter (ADC), calibration memory, and digital signal processing. It also includes a Digital-to-Analog Converter (DAC) with an output buffer to support analog voltage output and a 4m A- 20m A current loop. It is designed for sensor applications such as strain gauges, pressure, force, and temperature.
This Sensor AFE has both analog and digital outputs. The digital 1-Wire/I2C interfaces program the calibration memory, the front-end Programmable gain amplifier (PGA)'s gain, and the internal current source that drives the sensors' bridge. The digital I2C interface can also be used to retrieve the digital output data and generate alarms.
The MAX40109 operates from 3V to 36V, is available in the thin quad flat no-lead (TQFN) package and wafer level package (WLP). It is specified over the -40°C to +125°C operating temperature...
