XR10910IL40-F

Overview

The XR10910IL40-F is a sensor interface analog front-end (AFE) manufactured by MaxLinear. It integrates a 16:1 differential multiplexer, programmable gain instrumentation amplifier, offset correction DAC, and voltage reference within a 6 mm x 6 mm QFN-40 package. The device supports 2.7 V to 5 V analog supply and 1.8 V to 5 V digital supply ranges. Key electrical parameters include a maximum power supply current of 556 µA, maximum input offset voltage of 1 mV, and maximum input bias current of 100 pA. It offers eight fixed gain settings ranging from 2 V/V to 760 V/V with ±0.5% gain error.
