ADC12D040CIVS/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12D040CIVS/NOPB is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments, succeeding the National Semiconductor lineage. It operates at a sampling rate of 40 MSPS with a power consumption of 210 mW per channel when powered by a single 3V supply. The device utilizes a pipeline architecture with digital error correction and an on-chip sample-and-hold circuit to minimize die size while maintaining excellent dynamic performance. It features differential inputs for optimal noise rejection and provides parallel output data in offset binary format. The component is housed in a 48-lead LQFP package and supports operation over the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 12-bit resolution with 40 MSPS sampling rate
• Low power consumption of 210 mW per channel at 3V supply
• On-chip sample-and-hold circuit and internal reference buffer
• Digital error correction for improved linearity and accuracy

Analog To Digital Converters (ADC) Applications

• Intermediate frequency (IF) sampling in communication systems
• Software-defined radio (SDR) receivers
• Medical imaging equipment requiring high-speed data acquisition
• Test and measurement instruments

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12DL040 family, which includes dual-channel variants of the single-channel ADC12040. While originally developed under National Semiconductor, production and support were transferred to Texas Instruments following the acquisition. The 'CIVS' suffix indicates the commercial/industrial temperature grade and the 48-lead LQFP package type, while '/NOPB' denotes a lead-free, halogen-free RoHS-compliant version without black polymer marking.

Analog To Digital Converters (ADC) Replacement Considerations

For direct pin-compatible replacements within the same family, consider the ADC12DL040 or ADC12DL080 (80 MSPS variant). Single-channel equivalents like the ADC12040 may require architectural adjustments but share similar interface characteristics.
