The ADC3661, ADC3662, and ADC3663 (ADC366x) family of devices are low-noise, ultra-low power, 16- bit, 10-MSPS to 65-MSPS, high-speed, dual-channel, analog-to-digital converters (ADCs). Designed for low noise performance, these devices deliver a noise spectral density of –158 dBFS/Hz combined with great linearity and dynamic range. The ADC366x offers good dc precision together with IF sampling support making these devices suitable 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 power consumption that scales well with lower sampling rates.
