The ADC3681, 82, 83 (ADC368x) is a low noise, ultra-

low power 18-bit 65 MSPS high-speed dual channel

ADC family. Designed for lowest noise performance, it

delivers a noise spectral density of -160 dBFS/Hz

combined with excellent linearity and dynamic range.

The ADC368x offers excellent DC precision together

with IF sampling support which makes it ideally suited

for a wide range of applications. High-speed control

loops benefit from the short latency as low as only 1

clock cycle. The ADC consumes only 94 mW/ch at 65

Msps and its power consumption scales very well with

lower sampling rates.

•

The ADC368x uses a serial LVDS (SLVDS) interface

to output the data which minimizes the number of

digital interconnects. The device supports two-lane,

one-lane and half-lane options. The ADC36xx is a pin

to pin compatible family of ADCs with 16 and 18-bit

resolution and different speed grades. It comes in a

40-pin QFN package (5 x 5mm) and supports the

extended industrial temperature range from -40 to

+105⁰C.
