ADC12J4000NKE

Analog To Digital Converters (ADC) Overview

The ADC12J4000NKE is a 12-bit, 4 GSPS RF-sampling analog-to-digital converter from Texas Instruments. It features a folding interpolating architecture and outputs data via the JESD204B interface. The device operates on 1.2 V and 1.9 V power supplies within a -40°C to +85°C temperature range. Key performance metrics include an effective number of bits (ENOB) of 8.8 bits, a spurious-free dynamic range (SFDR) of 70 dB, and a signal-to-noise and distortion ratio (SINAD) of 54.8 dB. Differential nonlinearity is specified at +/- 0.25 LSB, with a typical power consumption of 1.6 W in a VQFN-68 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NKE' against the manufacturer's official datasheet to confirm pinout and packaging details. Ensure export control documentation is prepared if required by local regulations. Confirm that the ordering information matches the exact revision level needed for your design integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, ultra-high-speed 12-bit conversion is required at 4 GSPS. Compare against the dual-channel ADC12DJ4000 if multiple independent inputs are necessary. Evaluate the integrated DDC capabilities against external processing requirements to determine system complexity reduction benefits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12J4000 series, designed for high-performance RF sampling. It serves as a successor to lower-speed variants like the ADC12J1600, offering increased throughput while maintaining similar interface standards. The series targets applications demanding wide instantaneous bandwidth with high linearity.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12DJ4000 is a dual-channel alternative within the same family. Verify pin compatibility and software configuration differences before substitution. Other manufacturers offer comparable speeds but may require different clocking or interface adaptations.
