ADC12DS080CISQE/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12DS080CISQE/NOPB is a dual-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It supports sampling rates up to 80 MSPS using a differential pipeline architecture with integrated digital error correction and on-chip sample-and-hold circuits. The device operates from a single +3.0V or +3.3V supply and features serial LVDS outputs for data transmission. Key electrical specifications include a signal-to-noise ratio of 70 dBFS at an input frequency of 170 MHz and an integral nonlinearity of ±1.5 LSB. It utilizes a 60-pin WQFN package (9x9x0.8mm) and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CISQE' against the manufacturer's official documentation to confirm the exact temperature grade and packaging configuration. Ensure that the required operating voltage aligns with the single +3.0V or +3.3V specification. Confirm interface compatibility with the serial LVDS output format before integration into the system design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel conversion at 12-bit resolution and 80 MSPS speed is required. The differential input structure supports a 2V full-scale differential input swing. Consider the power consumption characteristics, which drop significantly in shutdown mode, if low-power standby operations are necessary for the application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12DS080 series of high-performance CMOS analog-to-digital converters. The series is characterized by its pipeline architecture and integration of digital error correction. The specific model indicates a commercial or industrial variant housed in a compact WQFN package suitable for space-constrained designs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacements must match the 12-bit resolution, 80 MSPS sampling rate, and dual-channel configuration. Verify pinout compatibility with the 60-pin WQFN footprint. Alternative devices should support similar supply voltages and LVDS output interfaces to maintain system integrity without redesigning the digital interface.
