Exar Corporation Announces the XR18910

Exar Corporation, a supplier of analog mixed-signals products for consumer and infrastructure markets, has released the XR18910, an analog front sensor interface for high channel count and functionality.

The device measures at 3.5x3.5mm, offers 14-bit signal path linearity and is designed to connect analog sensors to a microcontroller or FPGA (field-programmable gate array) with an embedded ADC.

The onboard 10-bit DAC offers ±560mV of offset correction and allows an independent offset value for each of the eight differential inputs.  The programmable gain instrumentation amplifier offers eight fixed-gain settings (from 2V/V to 760V/V), ensuring the amplified sensor signal falls within the optimum input range of the downstream ADC, according to a press release.

“The XR18910 provides designers with an easy-to-use sensor interface that calibrates and amplifies signals from eight different analog sensors, improving overall system sensitivity and accuracy,” said Dale Wedel, vice president of high performance analog.  “It offers more functionality with lower power than discrete solutions and is suitable for a variety of applications such as force sensing, pod racers and power monitoring for solar energy and data centers. It also occupies a significantly smaller footprint than our original XR10910 16:1 sensor interface, making it more attractive when fewer channels are required.”
