AD9680BCPZ-1000

The AD9680BCPZ-1000 is a 14-bit, 1 GSPS dual analog-to-digital converter (ADC) from Analog Devices. It features a pipelined architecture with differential inputs and a JESD204B (Subclass 1) serial data interface for high-speed data transfer. The device operates from 1.25V, 2.5V, and 3.3V supply rails and consumes 1.65 W per channel at 1 GSPS default settings.

Key performance metrics include a signal-to-noise ratio (SNR) of 65.3 dBFS at 340 MHz input and 60.5 dBFS at 1 GHz, and a spurious-free dynamic range (SFDR) of 85 dBFS at 340 MHz and 80 dBFS at 1 GHz. The effective number of bits (ENOB) is 10.8 bits at 10 MHz. The analog input bandwidth is 2 GHz, and the input voltage range is programmable from 1.46 V p-p to 1.94 V p-p, with a nominal 1.70 V p-p for this speed grade.

This ADC is designed for communications applications such as multiband digital receivers, 3G/4G and LTE base stations, software-defined radios, and general-purpose data acquisition systems. It includes features like two integrated wideband digital processors, amplitude detect bits for AGC, and flexible JESD204B lane configurations.

The device is offered in a 64-WFQFN exposed pad CSP package with a supplier device package of 64-LFCSP (9x9 mm). It is surface mount and rated for an operating temperature range of -40°C to +85°C. The AD9680BCPZ-1000 is RoHS3 compliant (unverified), MSL level 1, and REACH unaffected.
