ADC12DS105CISQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12DS105CISQ/NOPB is a dual-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It operates at a sampling rate of 105 MSPS with serial LVDS outputs. The device features an input bandwidth up to 1 GHz and supports mid-frequency sampling without requiring down-conversion stages. Power consumption is approximately 400 mW at 3.0 V supply voltage. Key performance metrics include a Signal-to-Noise Ratio (SNR) of 70 dB at high input frequencies and an Effective Number of Bits (ENOB) of 11.9 bits at 105 MSPS. The component utilizes a pipeline architecture and is housed in a 60-pin LLP package.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC12DS/ADC14DS family of high-performance pipeline ADCs from National Semiconductor (now Texas Instruments). These devices are designed for applications requiring high linearity and dynamic range. The series ensures pin compatibility across different resolutions, allowing system upgrades from 12-bit to 14-bit configurations while maintaining the same footprint and interface standards.

Analog To Digital Converters (ADC) Replacement Considerations

For single-channel requirements, consider the ADC12D105. For higher resolution needs within the same form factor, the ADC14DS105 offers 14-bit performance. If parallel CMOS outputs are preferred over LVDS, the ADC12DC105 series is available.
