Sensor Interface Connects Multiple Sensors to MCUs or FPGAs

Exar Corp. has announced the XR10910, a new sensor interface analog front end (AFE) for the calibration of sensor outputs. The XR10910 features an onboard 16:1 differential multiplexer, offset correction DAC, programmable gain instrumentation amplifier, and voltage reference. In addition, it provides 14-bit signal path linearity and is designed to connect multiple bridge sensors to a microcontroller or FPGA with an embedded ADC.EX041_Exar

Operating from from 2.7- to 5-V supplies, the XR10910 has a wide digital supply range of 1.8 to 5 V. It typically consumes 457 µA of supply current and offers a sleep mode for reducing the supply current to 45 µA.

The XR10910 is available in a 6 mm × 6 mm QFN package. Pricing starts at $8.10 each for 1,000-piece quantities.
