Overview
The ADS52J65IRGCR is an 8-channel, 16-bit analog-to-digital converter (ADC) produced by Texas Instruments. This device is designed using CMOS process and innovative circuit techniques to operate at low power while providing high signal-to-noise ratio (SNR) performance. It features a 2-Vpp full-scale input and achieves an idle SNR of 80 dBFS and a full-scale SNR of 78 dBFS at 10 MHz. The ADC is suitable for a wide range of high-frequency applications, including medical imaging, radar, and spectroscopy.
