AD9694BCPZ-500

The AD9694BCPZ-500 is a 14-bit, 500 MSPS quad analog-to-digital converter (ADC) from Analog Devices. It employs a pipelined architecture with differential inputs and an internal voltage reference. The device supports simultaneous sampling across four channels and provides JESD204B serial digital outputs with lane rates up to 15 Gbps.

Key electrical specifications include a typical SNR of 66.8 dBFS and SFDR of 82 dBFS at 305 MHz input frequency (1.80 V p-p range). Total power consumption is 1.66 W at 500 MSPS, with 415 mW per channel. The analog input full power bandwidth is 1.4 GHz, and the differential input range is programmable from 1.44 V p-p to 2.16 V p-p (nominal 1.80 V p-p).

The ADC operates from multiple supply voltages: 0.975 V (AVDD1, DRVDD1, DVDD), 1.8 V (AVDD2, DRVDD2, SPIVDD), and 2.5 V (AVDD3). It includes on-chip dithering, amplitude detect bits for AGC, and four integrated digital down converters with 48-bit NCO and cascaded half-band filters. The clock input accepts differential signals with integer divide ratios of 1, 2, 4, or 8.

The device is housed in a 72-lead LFCSP-VQ (10x10 mm) package with exposed pad for surface mount assembly. It operates over the industrial temperature range of -40°C to +105°C.
