LMP90097MHE/NOPB

Analog Front End (AFE) Overview

The LMP90097MHE/NOPB is a low-power, four-channel delta-sigma analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a 24-bit resolution and supports sampling rates up to 214.6 samples per second. The device utilizes single-ended inputs and integrates a programmable gain amplifier (PGA). It operates on an analog supply voltage ranging from 2.85 V to 5.5 V and a digital supply voltage from 2.7 V to 5.5 V. Communication is handled via an SPI interface. The component is housed in a 28-pin HTSSOP package with an exposed pad and functions within a temperature range of -40°C to +125°C.
