ADC12D1800CIUT

Analog To Digital Converters (ADC) Overview

The ADC12D1800CIUT is a dual-channel, high-speed analog-to-digital converter manufactured by Texas Instruments. It operates with a resolution of 12 bits and supports sampling rates up to 3.6 GSPS in interleaved mode or 1.8 GSPS per channel in dual mode. The device features a folding interpolating architecture with differential analog inputs and LVDS digital outputs. It requires a single 1.9 V analog supply and a 1.8 V to 2 V digital supply. Key performance metrics include a typical SNR of 58.5 dB at 1.8 GSPS and an ENOB of 9.4 bits. The component is housed in a 292-ball thermal-enhanced BGA package and is rated for industrial operating temperatures ranging from -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIUT' against the official datasheet to confirm the temperature grade and packaging type. Ensure compliance with export control regulations if applicable. Confirm that the ordering information matches the exact pinout and electrical specifications required for the design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high dynamic range and ultra-high speed are required for wideband signal acquisition. Compare power consumption and noise density against lower-resolution alternatives. Ensure the host FPGA or ASIC can handle the parallel LVDS data throughput and timing constraints associated with 3.6 GSPS operation.

Analog To Digital Converters (ADC) Part Context
