SBAS991 February 2021 ADC3663
The ADC366x is a low noise, ultra-low power 16-bit high-speed dual channel ADC 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 ADC366x is equipped with an on-chip 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. Single ended as well as differential input signaling is supported.
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 ADC366x 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 ADC366x 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.
