3 Description

The ADC358x is a low noise, ultra-low power 18-bit

65 MSPS high-speed ADC family. Designed for low

noise performance, it delivers a noise spectral density

of -160 dBFS/Hz combined with excellent linearity

and dynamic range. The ADC358x offers very good

DC precision together with IF sampling support which

makes it suited for a wide range of applications. Highspeed

control loops benefit from the short latency

as low as only 1 clock cycle. The ADC consumes

only 119 mW at 65 Msps and its power consumption

scales well with lower sampling rates.

The ADC358x uses a serial LVDS (SLVDS) interface

to output the data which minimizes the number of

digital interconnects. The device supports a one-lane

and two-lane option. The ADC358x is a pin to pin

compatible family with different speed grades. It

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

supports the extended industrial temperature range

from -40 to +105?C.
