The ADC364x family of devices are low-noise, ultra-low power, 14-bit, 10-MSPS to 65-MSPS dual-channel, high-speed analog-to-digital converters (ADCs). Designed for low power consumption, these devices deliver a noise spectral density of –155 dBFS/Hz, combined with excellent linearity and dynamic range. The ADC364x offers very good dc precision, together with IF sampling support, which make the device an excellent choice for a wide range of applications. High-speed control loops benefit from the short latency of only one clock cycle. The ADC consumes only 72 mW/ch at 65 MSPS, and power consumption scales well with lower sampling rates.

The ADC364x use a DDR or serial CMOS interface to output the data offering lowest power digital interface, together with flexibility to minimize the number of digital interconnects. These devices are a pin-to-pin compatible family with different speed grades. These devices support the extended industrial temperature range of –40 to +105⁰C.
