ADC3562IRSBR

The ADC3561, ADC3562, ADC3563 (ADC356x) family of devices are a low-noise, ultra-low power, 16-bit, 10-MSPS to 65-MSPS, high-speed analog-to-digital converters (ADCs). Designed for low power consumption, these devices deliver a noise spectral density of –158 dBFS/Hz combined with excellent linearity and dynamic range. The ADC356x offers good DC precision together with IF sampling support making the device suitable for a wide range of applications. High-speed control loops benefit from the short latency of only one clock cycle. The ADC consumes only 122 mW at 65 MSPS and power consumption that scales well with lower sampling rates. The ADC356x uses a serial LVDS (SLVDS) interface to output the data which minimizes the number of digital interconnects. The device supports two-, one- and half-lane options. The ADC356x and ADC358x are a pin-to-pin compatible family with 16 and 18-bit resolution and different speed grades. The devices come in a 40-pin QFN package (5 × 5 mm), and supports the extended industrial temperature range from -40 to +105°C.
