The ADS92x4R is a pin-compatible, high-speed, dual, simultaneous-sampling, analog-to-digital converters (ADC) with an integrated reference and reference buffer. The device can operate on a single 5-V supply and supports unipolar, fully differential analog input signals with excellent DC and AC specifications. The device has excellent AC performance with analog input frequencies up to 1.5 MHz, which makes the device suitable for wide-bandwidth data acquisition (DAQ) systems.
The device supports SPI-compatible serial (enhanced-SPI) and byte-wide parallel interfaces, making the device easy to pair with a diversity of microcontrollers, digital signal processors (DSPs), and field-programmable gate arrays (FPGAs). This device also supports a data averaging feature that provides an AC performance boost in noisy environments.
The device comes in a space-saving, 5-mm × 5-mm, VQFN package. The ADS92x4R is specified for the extended temperature range of –40°C to +125°C.
