XR18910
8:1 Sensor Interface Analog Front End
Description
The XR18910 is a unique sensor interface integrated circuit with an onboard 8:1 multiplexer, offset correction Digital-to-Analog Converter (DAC), instrumentation amplifier and voltage reference. The XR18910 is designed to integrate multiple bridge sensors with a Microcontroller (MCU) or Field-Programmable Gate Array (FPGA).
The integrated offset correction DAC provides digital calibration of the variable and in many cases substantial offset voltage generated by the bridge sensors. The DAC is controlled by an I2C compatible 2-wire serial interface. The serial interface also provides the user with easy controls to the XR18910’s many functions such as input and gain selection.
