3 Description

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 +105?C.
