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. Thedevice has excellent AC performance with analog input frequencies up to 1.5 MHz, which makes thedevice suitable for wide-bandwidth data acquisition (DAQ) systems.

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). This device also supports a dataaveraging feature that provides an AC performance boost in noisy environments.

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.
