ADC12J2700NKE

Analog To Digital Converters (ADC) Overview

The ADC12J2700NKE is a 12-bit RF-sampling analog-to-digital converter manufactured by Texas Instruments. It supports a sampling rate of up to 5.4 GSPS in single-channel mode or 2.7 GSPS in dual-channel mode, enabling direct RF sampling from DC to over 10 GHz. The device features an 8.0 GHz full-power input bandwidth and utilizes the JESD204B interface with up to 16 serialized channels for deterministic latency. Key performance metrics include a typical SFDR of 70 dBc and an ENOB of 8.8 bits at Nyquist. It operates on 1.2 V and 1.9 V supplies within a -40°C to +85°C temperature range.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and temperature grade. Ensure compatibility with required export documentation if shipping from the United States. Confirm that the selected variant matches the intended system voltage and interface requirements before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when designing systems requiring direct RF sampling without intermediate downconversion stages. Evaluate the trade-off between single-channel high-speed operation and dual-channel parallel processing based on system bandwidth needs. Ensure the design accommodates the specific power supply rails and thermal dissipation requirements associated with high-speed digital interfaces.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12DJ2700 family of ultra-high-speed RF-sampling ADCs. It shares architectural similarities with other members like the ADC12DJ3200 but offers distinct sampling rates optimized for specific bandwidth applications. The NKE suffix typically denotes a specific commercial-grade packaging configuration within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include other devices from the ADC12DJ series such as the ADC12DJ2700AAV or ADC12DJ2700ZEG, provided they match the exact pinout and electrical specifications. Verify functional equivalence regarding JESD204B lane counts and power consumption before substitution.
