3 Description

The ADC3683-SP is a low noise, ultra-low power 18-

bit 65MSPS high-speed dual channel ADC. Designed

for lowest noise performance, the device delivers a

noise spectral density of ?160dBFS/Hz combined with

excellent linearity and dynamic range. The ADC3683-

SP offers DC precision together with IF sampling

support making it designed 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 94mW/ch at 65Msps and the

power consumption scales well with lower sampling

rates.

The device 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 device is pin-topin

compatible with the 14-bit, 125MSPS ADC3664-

SP. The device comes in a 64-pin CFP package

(10.9mm x 10.9mm), and supports a temperature

range from ?55°C to +105°C.
