ADC12DC080CISQE

Analog To Digital Converters (ADC) Overview

The ADC12DC080CISQE is a high-speed, dual-channel analog-to-digital converter manufactured by National Semiconductor. It features two independent 12-bit ADC cores operating at sampling rates up to 80 MSPS. The device utilizes a low-power architecture designed for applications requiring high performance with minimal energy consumption. Key electrical parameters include a single +3.3V power supply requirement and differential analog input configuration. The component is housed in a 48-lead TSSOP package with an exposed pad, suitable for surface-mount assembly.

Analog To Digital Converters (ADC) Feature Summary

• Dual-channel 12-bit resolution with simultaneous sampling capability
• High-speed operation supporting up to 80 MSPS per channel
• Low-power design optimized for battery-operated systems
• Integrated on-chip voltage reference and output registers

Analog To Digital Converters (ADC) Applications

• Medical imaging equipment such as ultrasound systems
• Industrial process control and data acquisition
• Communications infrastructure and signal processing
• Test and measurement instrumentation

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin, as National Semiconductor assets were acquired by Texas Instruments. Confirm the specific suffix 'CISQE' corresponds to the commercial temperature range and tape-and-reel packaging. Ensure compatibility with the 48-lead TSSOP footprint during procurement planning.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel synchronization is required without external clocking complexity. Compare against single-channel alternatives if only one path is needed to reduce cost. Verify that the 80 MSPS speed meets the Nyquist requirements of the target signal bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12D family of dual converters from National Semiconductor. It serves as a successor to earlier single-channel high-speed ADCs, offering integrated dual paths to save board space. The device represents the company's focus on high-performance mixed-signal solutions before the industry consolidation.

Analog To Digital Converters (ADC) Replacement Considerations

Texas Instruments lists the ADC12D080CISQ as a direct equivalent. Verify pinout and register compatibility before substitution. Other manufacturers may offer similar specs but require interface adjustments.
