ADC12J4000NKET

Analog To Digital Converters (ADC) Overview

The ADC12J4000NKET is a 12-bit, 4 GSPS RF-sampling analog-to-digital converter from Texas Instruments. It features an integrated Digital Down Converter (DDC) and supports JESD204B interfaces. The device operates with analog and digital supply voltages of 1.2 V and 1.9 V. Key performance metrics include a Spurious-Free Dynamic Range (SFDR) of 70 dB, Signal-to-Noise and Distortion Ratio (SINAD) of 54.8 dB, and an Effective Number of Bits (ENOB) of 8.8 bits. Differential Nonlinearity (DNL) is specified at +/- 0.25 LSB. It functions within a temperature range of -40°C to +85°C and consumes approximately 1.6 W of power.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NKET' against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compliance with export control regulations if shipping from the United States, as this component may require additional documentation for international transit.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, ultra-high-speed sampling rate is required alongside on-chip digital signal processing capabilities. The integrated DDC reduces FPGA logic load by performing complex mixing and decimation internally. Verify that the system clock jitter requirements align with the device's phase noise sensitivity to maintain target SNR performance.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12J1600 family of GSPS ADCs with integrated DDCs. It represents a higher speed variant compared to the 1.6 GSPS models in the same series, offering increased bandwidth while maintaining similar interface standards and architectural features for high-frequency signal acquisition.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12J1600 serves as a lower-speed alternative within the same product family. For quad-channel requirements, consider the ADC12DJ4000 series. Verify pin compatibility and software register settings when migrating between these variants.
