3 Description

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

65 MSPS high-speed 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 ADC358x offers very good 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 119 mW at 65 Msps and its

power consumption scales very 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 (5x5mm) and

supports the extended industrial temperature range

from -40 to +105⁰C.
