ADC12QJ800AAV

Analog To Digital Converters (ADC) Overview

The ADC12QJ800AAV is a quad-channel, 12-bit analog-to-digital converter (ADC) from Texas Instruments. It operates at a maximum sampling rate of 800 MSPS with a full-power input bandwidth of 6 GHz. The device features a JESD204C serial interface supporting baud rates up to 17.16 Gbps and includes an internal PLL/VCO for clock generation. Key performance metrics include an SNR of 57.6 dBFS and an ENOB of 9 bits at 97 MHz. Power consumption is 415 mW per channel at 800 MSPS. It utilizes a 144-ball FCBGA package.

• Electronic warfare (SIGINT, ELINT)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to ensure correct package type and temperature rating. Confirm that the component meets all necessary environmental standards required for the intended deployment environment before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this model when four independent channels are required for simultaneous signal acquisition. Ensure the host system supports the JESD204C protocol and can handle the specified SerDes baud rates. Verify that the power supply rails match the 1.1 V and 1.9 V requirements defined in the datasheet.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12xJ800 family, which also includes dual-channel (ADC12DJ800) and single-channel (ADC12SJ800) variants. All members share identical core specifications regarding resolution, sampling speed, and interface capabilities, differing only in the number of available analog input channels.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the ADC12DJ800AAV and ADC12SJ800AAV. These parts maintain identical electrical characteristics but offer reduced channel counts. Cross-family substitution requires verification of pin compatibility and interface protocol support.
