ADC12D1000CIUT

Analog To Digital Converters (ADC) Overview

The ADC12D1000CIUT is a dual-channel, 12-bit ultra-high-speed analog-to-digital converter manufactured by Texas Instruments. It operates in two primary modes: interleaved mode at 2.0 GSPS or dual independent mode at 1.0 GSPS per channel. The device features a folding interpolating architecture with differential analog inputs and LVDS outputs. Key electrical specifications include a signal-to-noise ratio (SNR) of 54.6 dB, an effective number of bits (ENOB) of 9.6 bits, and a total power dissipation of approximately 3.51 W to 4.06 W. It utilizes a single 1.9 V analog supply and 1.8 V to 2 V digital supplies, housed in a 292-pin BGA package suitable for industrial temperatures ranging from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet to confirm pinout compatibility and RoHS status. Ensure that the ordering information matches the required temperature range and packaging format. Cross-reference the part number with official distributor catalogs to validate availability and ensure no obsolete revisions are selected for new designs.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic performance and flexible sampling rates are required for wideband signals. Compare the SNR and SFDR metrics against alternative devices if strict linearity is critical. Consider the power consumption profile relative to thermal management constraints on the PCB. Verify that the host FPGA or ASIC can support the parallel LVDS output interface timing requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC12D1x00 family of ultra-high-speed ADCs from Texas Instruments. It shares architectural similarities with the ADC10D1x00 series but offers higher resolution. The CIUT variant specifically denotes the commercial temperature grade and BGA packaging configuration within the broader product line designed for demanding RF and baseband processing tasks.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12D1600CIUT serves as a higher-speed alternative within the same family, supporting up to 3.2 GSPS in interleaved mode. Designers should verify pin compatibility and software register settings when migrating between these variants to ensure seamless integration without hardware redesign.
