The LMP93601 is an optimized Analog-Front-End (AFE) for occupancy detecting thermopile arrays up to 16 x 16 and thermopile mass flow sensors. The AFE combines excellent noise performance, low offset voltage, high gain, and low-power consumption at sampling rates ideal for monitoring thermopile sensors.

The LMP93601 is a precision, 16-bit, analog-to-digital converter (ADC) offered in a leadless WQFN-24 package. The device features three differential EMI hardened inputs, a low-noise, high-gain programmable gain amplifier (PGA), a level shifting voltage source, an internal reference, and a programmable sampling rate. The many integrated features and the simple control of the LMP93601 through an SPI-compatible interface ease precision measurements of thermopile sensor signals.
