ADC12DL040CIVS

Analog To Digital Converters (ADC) Overview

The ADC12DL040CIVS is a dual-channel, low-power monolithic CMOS analog-to-digital converter manufactured by Texas Instruments. It performs simultaneous sampling and conversion of two analog input signals into 12-bit digital words at a minimum sampling rate of 40 MSPS. The device utilizes a differential pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to minimize die size and power consumption while maintaining excellent dynamic performance. Operating on a single 3V supply, the ADC12DL040CIVS consumes only 210mW at full speed. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 68 dB at a 10 MHz input frequency, an Effective Number of Bits (ENOB) of 10.9 bits, and a Spurious-Free Dynamic Range (SFDR) of 80 dB. The part operates over an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix CIVS against the manufacturer's official documentation to confirm package type and temperature grade. Ensure compatibility with system voltage levels and clocking requirements before integration. Check for any recent lifecycle status updates or recommended replacements from Texas Instruments to ensure long-term availability.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel simultaneous sampling is required at 40 MSPS with low power constraints. The 3V supply operation makes it suitable for battery-powered or low-voltage systems. Consider the 12-bit resolution and dynamic performance metrics if high fidelity is needed for IF signals. Verify interface compatibility with downstream digital processors.

Analog To Digital Converters (ADC) Part Context

The ADC12DL040 series belongs to Texas Instruments' family of high-speed, low-power dual A/D converters. It is designed to replace older single-supply 5V devices with more efficient 3V alternatives. The 'CIVS' designation typically indicates a specific package variant and industrial temperature rating within the broader ADC12DL040 product line.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades such as the ADC12DL080 for higher speed requirements. Review Texas Instruments' official substitution guides for any newer generations with improved SNR or lower power consumption that maintain the same footprint.
