3 Description

The ADC3561, ADC3562, ADC3563 (ADC356x)

family of devices are a low-noise, ultra-low power,

16-bit, 10-MSPS to 65-MSPS, high-speed analog-todigital

converters (ADCs). Designed for low power

consumption, these devices deliver a noise spectral

density of –158 dBFS/Hz combined with excellent

linearity and dynamic range. The ADC356x offers

good DC precision together with IF sampling support

making the device suitable for a wide range of

applications. High-speed control loops benefit from

the short latency of only one clock cycle. The ADC

consumes only 122 mW at 65 MSPS and power

consumption that scales well with lower sampling

rates.

The ADC356x uses a serial LVDS (SLVDS) interface

to output the data which minimizes the number of

digital interconnects. The device supports two-, oneand

half-lane options. The ADC356x and ADC358x

are a pin-to-pin compatible family with 16 and 18-bit

resolution and different speed grades. The devices

come in a 40-pin QFN package (5 x 5 mm), and

supports the extended industrial temperature range

from -40 to +105⁰C.
