Designed to integrate with a microcontroller (MCU) or field-programmable gate array (FPGA), the XR10910 from Exar provides more design flexibility than single-chip solutions. The XR10910 offers higher available gain, lower offset, lower noise, smaller footprint, and faster design times than discrete solutions.

The XR10910 is a unique sensor interface analog front end that provides calibration of sensor outputs. It offers an on-board 16:1 differential multiplexer, offset correction DAC, programmable gain instrumentation amplifier, and voltage reference. This AFE provides a 14-bit signal path linearity and is designed to connect multiple bridge sensors with an MCU or FPGA with an embedded ADC.

The integrated DAC provides offset calibration for any offset voltage generated by bridge sensors, improving overall system sensitivity and accuracy. An independent offset value can be set for each of the 16 differential inputs. Eight fixed-gain settings ensure the amplified sensor signal falls within the optimum input range of the downstream ADC. The integrated LDO provides a regulated voltage to power the sensors. The XR10910's many functions are easily controlled by an I²C serial interface.
