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-to-

digital 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 very

good DC precision together with IF sampling support,

which makes 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 122 mW at 65 MSPS and its

power consumption scales very 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-, one-

and half-lane options. The ADC356x/8x is a pin to pin

compatible family with 16 and 18-bit resolution and

different speed grades. It comes in a 40-pin QFN

package (5x5mm) and supports the extended

industrial temperature range from -40 to +105⁰C.
