3 Description

The ADC12D1620QML uses a package redesign to achieve better ENOB, SNR, and X-talk compared to the ADC12D1600QML. As is its predecessor, the ADC12D1620QML is a low-power, high-performance CMOS analog-to-digital converter (ADC) that digitizes signals at a 12-bit resolution at sampling rates up to 3.2 GSPS in an interleaved mode. It can also be used as a dual-channel ADC for sampling rates up to 1.6 GSPS. For sampling rates below 800 MHz, there is a low-sampling power-saving mode (LSPSM) that reduces power consumption to less than 1.4 W per channel (typical). The ADC can support conversion rates as low as 200 MSPS.
