XR10910 - Exar

XR10910 16:1 Sensor Interface

The XR10910 is a unique sensor interface integrated circuit with an on-board 16:1 multiplexer, offset correction DAC, instrumentation amplifier and voltage reference. The XR10910 is designed to integrate multiple bridge sensors with a microcontroller (MCU) or field-programmable gate array (FPGA). The integrated offset correction DAC provides digital calibrat.

Features

make the XR10910 well suited for both industrial and consumer applications using bridge sensors. F E AT U R E S
