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 +105⁰C.
