ADC12QJ800AAVTQ1

Analog To Digital Converters (ADC) Overview

The ADC12QJ800AAVTQ1 is a quad-channel, 12-bit analog-to-digital converter (ADC) from the ADC12xJ800-Q1 family. It operates at a maximum sampling rate of 800MSPS with a full-power input bandwidth of 6GHz. The device features a non-interleaved architecture and an internal dither mechanism to reduce high-order harmonics. Performance specifications include a signal-to-noise ratio (SNR) of 57.6dBFS and an effective number of bits (ENOB) of 9 bits at 97MHz. It utilizes a JESD204C serial interface supporting up to 8 SerDes lanes with baud rates up to 17.16Gbps. Power consumption is 415mW per channel at 800MSPS. The component is housed in a 144-ball FCBGA package and is qualified for automotive applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm pinout compatibility and functional configuration. Ensure that the selected variant matches the required channel count and interface encoding modes. Cross-reference the package marking with the datasheet to validate authenticity before integration into production designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a high-speed, multi-channel ADC with integrated serialization is required for automotive radar or LiDAR architectures. The 6GHz bandwidth supports direct RF sampling, reducing front-end complexity. Evaluate power consumption requirements across all four channels to ensure adequate thermal management within the FCBGA enclosure.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADC12xJ800-Q1 family, which includes dual and single-channel variants sharing the same core architecture. The family is designed specifically for high-performance automotive sensing applications requiring low latency and high dynamic range. All variants utilize the same 144-ball FCBGA footprint to maintain board layout consistency across different channel configurations.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12DJ800-Q1 serves as a dual-channel alternative within the same family. The ADC12SJ800-Q1 provides a single-channel option. These parts share identical electrical characteristics and packaging but differ in active channel count.
