Dual-channel SAR ADCs ideal for wide-bandwidth data acquisition systems

06-11-2019 | Texas Instruments | Semiconductors

Texas Instruments ADS92x4R dual-channel SAR ADCs provide pin-compatible, high-speed, simultaneous-sampling with an integrated reference and reference buffer. The ADCs run from a single 5V supply and supports unipolar operation. The device provides fully differential analog input signals with good DC and AC specifications. With high AC performance, the ADCs offer analog input frequencies up to 1.5MHz, which makes the device ideal for wide-bandwidth data acquisition (DAQ) systems.


The ADCs support enhanced-SPI and byte-wide parallel interfaces, making the device simple to pair with a variety of microcontrollers, DSPs, and FPGAs. A data averaging feature gives an AC performance boost in noisy environments on the ADCs.


The device is offered in a space-saving, 5mm x 5mm, VQFN package and is specified for the extended temperature range of –40C to +125C.


Typical applications include optical encoders, SONAR receivers, optical networking: EDFA gain-control loop, power-quality measurement, digital power supply, i/q demodulators, medical imaging: CT scanners, MRI scanners, and impedance analysers.
