The ADC358x is a low noise, ultra-low power 18-bit high-speed ADC family supporting sampling rates up to 65 MSPS. It offers very good DC precision together with IF sampling support which makes it ideally suited for a wide range of applications. The ADC358x is equipped with an internal reference option but it also supports the use of an external, high precision 1.6 V voltage reference or an external 1.2 V reference which is buffered and gained up internally. Because of the inherent low latency architecture, the digital output result is available after only one to two clock cycles.

An optional programmable digital down converter enables external anti-alias filter relaxation as well as output data rate reduction. The digital filter provides a 32-bit programmable NCO and supports both real or complex decimation. The internal DDC mux enables use of two decimation filters with independent NCOs for dual band support (using channel B output interface).

The ADC358x uses a serial LVDS (SLVDS) interface to output the data which minimizes the number of digital interconnects. The device supports a two-lane (2-wire), a one-lane (1-wire) and a half-lane (1/2-wire) option. The ADC358x includes a digital output formatter which supports output resolutions from 14 to 20-bit.

The device features and control options can be set up either through pin configurations or via SPI register writes.
