Dual-channel, 18-bit, 65-MSPS, low-noise, ultra-low-power, low-latency ADC

The ADC3681, 82, 83 (ADC368x) is a low noise, ultra-low power 18-bit 65 MSPS high-speed dual channel 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 ADC368x offers excellent DC precision together with IF sampling support which makes it 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 94 mW/ch at 65 Msps and its power consumption scales well with lower sampling rates.

The ADC368x uses a serial LVDS (SLVDS) interface to output the data which minimizes the number of digital interconnects. The device supports two-lane, one-lane and half-lane options. The ADC36xx is a pin to pin compatible family of ADCs with 16 and 18-bit resolution and different speed grades. It comes in a 40-pin QFN package (5 x 5mm) and supports the extended industrial temperature range from -40 to +105⁰C.
