ADC12DC105CISQ/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12DC105CISQ/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 full power bandwidth of 1 GHz. The device utilizes a differential pipeline architecture featuring digital error correction and on-chip sampling hold circuits. It supports single +3.0V or +3.3V supply operation and includes an internal 1.2V reference. Key electrical parameters include a typical SNR of 69 dBFS and SFDR of 83 dBFS at 170 MHz input frequency. Power consumption is approximately 690 mW at 3.0V and 800 mW at 3.3V. The component is housed in a 60-lead WQFN package (9x9 mm) suitable for industrial temperature ranges from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CISQ' against official datasheets to confirm industrial temperature range (-40°C to +85°C) and RoHS compliance status. Confirm package marking and lot traceability requirements prior to ordering. Ensure compatibility with existing board layouts regarding the 60-lead WQFN footprint and thermal pad connections.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed conversion is required within a compact form factor. The 1 GHz bandwidth supports wideband signal acquisition. Evaluate power constraints as the device consumes up to 800 mW. Consider the availability of the evaluation board ADC12DC105EB/NOPB for initial design validation and performance testing during the development phase.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12D family of high-speed converters from Texas Instruments. It shares architectural similarities with the ADC12DC105 but is distinguished by its specific commercial/industrial grade variant designation and packaging configuration. It serves as a direct replacement for legacy dual-channel ADCs requiring 12-bit resolution at 105 MSPS speeds.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional equivalents include the ADC12DC105CISQE/NOPB. Verify pinout compatibility and thermal characteristics when substituting. Cross-reference with ADC12DC080 if lower sampling rates suffice.
