AD9680BCPZRL7-1000

Analog To Digital Converters (ADC) Overview

The AD9680BCPZRL7-1000 is a dual-channel, 14-bit analog-to-digital converter (ADC) operating at a maximum sampling rate of 1 GSPS. It features JESD204B Subclass 1 coded serial digital outputs and supports flexible lane configurations. The device includes integrated digital downconverters (DDCs) with numerically controlled oscillators and half-band filters. Key electrical specifications include an SFDR of 85 dBFS at 340 MHz and 80 dBFS at 1 GHz, with an SNR of 65.3 dBFS at 340 MHz. It operates on 1.25 V, 2.5 V, and 3.3 V supplies, consumes 1.65 W per channel at 1 GSPS, and is housed in a 64-lead LFCSP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific speed grade suffix (-1000) matches the required 1 GSPS sampling rate during procurement. Confirm that the LFCSP-64 package orientation and pinout align with the target PCB footprint. Ensure power supply sequencing meets the 1.25 V, 2.5 V, and 3.3 V requirements specified in the datasheet. Check for RoHS compliance documentation if required by local regulations.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a dual-channel ADC with 14-bit resolution and 1 GSPS throughput is required. Consider the internal DDC capabilities if digital downconversion is needed to reduce data rates to the FPGA or processor. Evaluate the 2 GHz full-power bandwidth against the highest frequency component of the input signal. Verify that the system can support the differential clocking and JESD204B interface timing constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the AD9680 family from Analog Devices, which offers pin-compatible variants at different sampling speeds including 1.25 GSPS, 820 MSPS, and 500 MSPS. The -1000 suffix specifically denotes the 1 GSPS performance grade within this series. All variants share the same 64-lead LFCSP package and core functionality, differing primarily in AC performance metrics and maximum operating frequencies.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the AD9680BCPZRL7-1250 (1.25 GSPS), AD9680BCPZRL7-820 (820 MSPS), and AD9680BCPZRL7-500 (500 MSPS). When substituting, verify that the AC performance metrics such as SNR and SFDR meet the system requirements at the specific input frequencies.
