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 +105⁰C.
