ADC12D040CIVSX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12D040CIVSX/NOPB is a dual-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 40 MSPS using a differential pipeline architecture with digital error correction and on-chip sample-and-hold circuits. The device functions on a single +5V supply, consuming 600 mW at full speed, which reduces to 75 mW in power-down mode. It features a 32-lead TQFP package (7x7 mm) and supports digital output driver voltages from 2.4 V to 5 V. Key performance metrics include a typical Signal-to-Noise Ratio (SNR) of 68 dB and an Effective Number of Bits (ENOB) of 10.9 bits at a 10 MHz input frequency.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel differential pipeline architecture with integrated digital error correction
• Low-power operation with dedicated power-down mode for energy efficiency
• Flexible digital interface supporting 2.4 V to 5 V output driver compatibility
• Configurable output data formats including offset binary and two's complement

Analog To Digital Converters (ADC) Applications

• Intermediate Frequency (IF) sampling in communication systems
• Software-defined radio (SDR) front-end digitization
• Medical imaging equipment requiring high dynamic range
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIVSX' against the official Texas Instruments datasheet to confirm package type and tape/reel specifications. Ensure the ordering part number matches the exact pinout and electrical characteristics required for your design. Cross-reference with authorized distributors to confirm current availability and lead times, as manufacturing statuses may change.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization and high dynamic performance are required at 40 MSPS. Compare SNR and SFDR specifications against system noise floors. Verify that the 5V analog supply and flexible digital I/O voltage ranges align with the target system's power rails and logic levels. Consider thermal dissipation requirements given the 600 mW power consumption at maximum sampling rates.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC12DLxx series of dual-channel converters from Texas Instruments. It shares architectural similarities with the ADC12D040 but includes specific packaging or revision identifiers in its part number. It complements single-channel variants like the ADC12040 by providing matched channel performance for differential applications without external matching requirements.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC12D040. For different resolution or speed requirements, consider the ADC12DL040 or ADC12DL065. Verify that any substitute maintains the 40 MSPS sampling rate and 12-bit resolution while ensuring compatible supply voltages and package dimensions.
