ADC12D2000RFIUT

Analog To Digital Converters (ADC) Overview

The ADC12D2000RFIUT is a 12-bit, single-channel RF sampling analog-to-digital converter (ADC) from Texas Instruments. It operates at a sampling rate of 4.0 GSPS in interleaved mode or 2.0 GSPS in dual ADC mode. The device supports direct input frequencies up to and above 2.7 GHz, extending usability beyond the third Nyquist zone. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 54.8 dB, an Effective Number of Bits (ENOB) of 8.7 bits, and a Spurious-Free Dynamic Range (SFDR) of 64.6 dBc at 498 MHz. Power consumption is typically 4.6 W for the interleaved configuration and 2.3 W per channel in dual mode. The component is housed in a lead-free 292-ball thermally enhanced BGA package.

• RADAR / LIDAR Systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against the manufacturer's documentation. The 'NOPB' suffix indicates a lead-free package, while its absence denotes a leaded package. Both variants utilize the same 292-ball BGA form factor. Confirm export compliance requirements as this product may require additional documentation for shipment from the United States. Ensure the design accounts for the thermal dissipation needs associated with the specified power consumption levels.

Analog To Digital Converters (ADC) Selection Notes

Select the ADC12D2000RFIUT when high-speed RF sampling above 2.7 GHz is required with 12-bit resolution. The device supports DESCLKIQ mode for high-bandwidth applications. Designers must account for the requirement to write max power settings to Register 6h via the Serial Interface to achieve rated performance for clock frequencies greater than 1.6 GHz. The pinout is compatible with the ADC1xD1x00 and ADC12Dx00RF families for potential board-level upgrades.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12D2000RF series of RF-sampling GSPS ADCs manufactured by Texas Instruments. It is designed to augment large Nyquist zones with excellent noise and linearity performance at RF frequencies. The device is part of a family that includes pin-compatible alternatives such as the ADC1xD1x00 and ADC12Dx00RF, facilitating system scalability and design reuse across different sampling rate requirements.

Analog To Digital Converters (ADC) Replacement Considerations

The datasheet notes pin compatibility with the ADC1xD1x00 and ADC12Dx00RF families. Verify functional equivalence and register compatibility before substituting these parts. No other specific replacement part numbers are documented in the provided source material.
