ADC12D2000RFIUT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12D2000RFIUT/NOPB 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 input. 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, thermally enhanced 292-ball BGA package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix against manufacturer documentation to confirm package type and environmental rating. The 'NOPB' suffix indicates a lead-free product. Confirm that the required external components, such as the 3.3 kΩ ±0.1% resistors for Rext and Rtrim terminals, are included in the procurement scope, as they are necessary for achieving rated linearity and input impedance calibration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed RF sampling is required directly at frequencies exceeding 2.7 GHz without intermediate mixing stages. Ensure the design accommodates the 4.6 W power dissipation in interleaved mode through adequate thermal management on the PCB. Verify that the host system can handle the high-speed LVDS output data rates and that the clocking architecture supports the required jitter specifications for the target application bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12D2000RF family of high-speed RF sampling ADCs. It is pin-compatible with other devices in the ADC1xD1x00 and ADC12Dx00RF series, facilitating potential design upgrades or replacements within existing hardware architectures. The device is designed for industrial temperature ranges (-40°C to +85°C) and utilizes a thermally enhanced BGA package to manage heat dissipation effectively.

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, as feature sets may vary between specific model numbers within the broader family.
