Description

The ADC3664 device is a low-noise, ultra-low power, 14-bit, 125-MSPS, high-speed dual channel ADC. Designed for lowest noise performance, the device delivers a noise spectral density of –156.9 dBFS/Hz combined with excellent linearity and dynamic range. The ADC3664 offers IF sampling support which makes the device ideally suited for a wide range of applications. High-speed control loops benefit from the short latency as low as one clock cycle. The ADC consumes only 100 mW/ch at 125 MSPS and its power consumption scales very well with lower sampling rates.

The ADC3664 uses a serial LVDS (SLVDS) interface to output the data which minimizes the number of digital interconnects. The device supports a two-lane, one-lane and half-lane option. The ADC3664 is pin-to-pin compatible with a family of 16-bit resolution ADCs. The device supports the extended industrial temperature range from –40 to +105⁰C.
