The ADS92x4R is a pin-compatible, high-speed, dual,simultaneous-sampling, analog-to-digital converters (ADC) with an integratedreference and reference buffer. The device can operate on a single 5-V supply and supportsunipolar, fully differential analog input signals with excellent DC and AC specifications.

The device supports SPI-compatible serial (enhanced-SPI) and byte-wide parallelinterfaces, making the device easy to pair with a diversity of microcontrollers, digital signalprocessors (DSPs), and field-programmable gate arrays (FPGAs).

The device comes in a space-saving, 5-mm × 5-mm, VQFN package. TheADS92x4R is specified for the extended temperature range of –40°C to+125°C.
