ADC12081CIVT

Analog To Digital Converters (ADC) Overview

The ADC12081CIVT is a 12-bit, 5 MHz self-calibrating pipelined analog-to-digital converter (ADC) manufactured by Texas Instruments, which acquired National Semiconductor. It features an internal sample-and-hold circuit and operates on a single 5 V supply. Key electrical specifications include a signal-to-noise ratio (SNR) of 68 dB, a spurious-free dynamic range (SFDR) typically exceeding 70 dB, and a power consumption of 105 mW. The device utilizes a parallel interface for data output and is housed in a 32-lead LQFP package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12081 family of high-speed, low-power ADCs originally developed by National Semiconductor and now supported by Texas Instruments following their acquisition. The 'C' suffix indicates commercial temperature range operation (-20°C to +75°C), while 'IVT' denotes the LQFP-32 package type.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC12191 (10 MHz) or ADC1241 series variants. Verify interface compatibility and thermal requirements when substituting.
