ADC12DC105CISQE/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12DC105CISQE/NOPB is a dual-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 105 MSPS with a parallel CMOS interface and supports a 2Vpp input range. The device consumes approximately 800mW at full speed. Although originally developed under National Semiconductor, the product line was integrated into Texas Instruments following their acquisition. This specific part number represents the commercial temperature grade variant in an exposed QFN package.

Analog To Digital Converters (ADC) Feature Summary

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12D family, which features high bandwidth and low power consumption suitable for intermediate frequency (IF) sampling applications. The 'QE' suffix indicates a specific tape and reel packaging configuration for the commercial temperature range (-40°C to +85°C). The device utilizes a 60-pin WQFN package measuring 9mm x 9mm.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12DC105CISQ/NOPB is a pin-compatible single-tape-and-reel alternative within the same series. For higher resolution requirements, the ADC14C105 series offers 14-bit performance with similar form factors and interfaces.
