ADC12SJ800AAVT

Analog To Digital Converters (ADC) Overview

The ADC12SJ800AAVT is a single-channel, 12-bit analog-to-digital converter (ADC) from the Texas Instruments ADC12xJ800 family. It operates at a maximum sampling rate of 800 MSPS with a full-power input bandwidth of 6 GHz. The device features a non-interleaved architecture and an internal dither function to reduce high-order harmonics. Performance specifications at –1dBFS include a signal-to-noise ratio (SNR) of 57.6 dBFS, an effective number of bits (ENOB) of 9 bits, and a spurious-free dynamic range (SFDR) of 62 dBFS at 97 MHz. It utilizes a JESD204C serial interface supporting baud rates up to 17.16 Gbps with 64B/66B and 8B/10B encoding modes. Power consumption is 830 mW at 800 MSPS, supplied by 1.1 V and 1.9 V rails.

Analog To Digital Converters (ADC) Feature Summary

• Non-interleaved architecture with internal dither for harmonic reduction
• JESD204C serialized interface with Subclass-1 support for deterministic latency
• Integrated PLL and VCO for optional internal sampling clock generation
• Timestamp input/output capability for pulsed system synchronization

Analog To Digital Converters (ADC) Applications

• Light detection and ranging (LiDAR)
• Multi-channel oscilloscopes and digitizers
• Wireless communications test equipment
• Electronic warfare (SIGINT, ELINT)

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'AAVT' against the manufacturer's current datasheet to confirm package type, temperature grade, and reel quantity. Ensure compatibility with JESD204C receivers and validate power supply requirements (1.1V and 1.9V) during integration. Cross-reference pin configurations for the FCBGA-144 package to ensure correct PCB layout alignment.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, high-speed 12-bit ADC is required for direct RF sampling applications up to S-band frequencies. Consider the integrated PLL if external clocking hardware needs to be minimized. Evaluate the 830 mW power consumption against thermal constraints in the target enclosure. Verify that the host FPGA or ASIC supports the JESD204C standard with compatible lane counts and encoding modes.

Analog To Digital Converters (ADC) Part Context

The ADC12SJ800AAVT belongs to the ADC12xJ800 family, which includes quad (ADC12QJ800) and dual (ADC12DJ800) channel variants. All members share identical core specifications, including 12-bit resolution, 800 MSPS sampling rate, and JESD204C interface capabilities. The primary distinction lies in the number of analog input channels and corresponding data lanes available on the serialized output.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional replacements within the same family include the ADC12DJ800AAVT (dual-channel) and ADC12QJ800AAVT (quad-channel). These parts share identical electrical characteristics and pinouts but offer additional channels. Verify that the increased channel count does not impact board space or power budget constraints.
