MAX40109
Description
The MAX40109 is a low-power, precision sensor interface SoC 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 4mA–20mA current loop.

- Analog Zero-Pressure Offset pensation
- High-Precision PGA Front-End with 20 Gain Options
- Analog and Digital Outputs
- Digital 1-Wire, Power Line munication (PLC) and I2C interfaces
- Calibration Memory with Third-Order Polynomial for pensation from Temperature and Non-Linearity
- Internal Electromagnetic Interference (EMI) Rejection
- Supply Voltage Range: 3V to 36V
- Low 2mA (typ) Supply Current
