Description for the ADC3581
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. High-speed 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.
