ADC12EU050CIPLQ

Analog To Digital Converters (ADC) Overview

The ADC12EU050CIPLQ is an octal, 12-bit continuous-time sigma-delta analog-to-digital converter (ADC) manufactured by National Semiconductor. It operates at a sampling rate of 50M samples per second with a power consumption of 44 mW per channel, totaling 350 mW for the device. The converter features a resistive-input impedance architecture using op-amp filters, eliminating the need for external sample-and-hold amplifiers. It includes a built-in low-pass filter with an alias-free signal sampling bandwidth of up to 25 MHz and incorporates real-time overload recovery (IOR) functionality.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIPLQ' against the official Texas Instruments or National Semiconductor datasheet to confirm package type, temperature range, and qualification status. Ensure the component source is traced to authorized distributors to avoid counterfeit parts, as National Semiconductor assets were acquired by Texas Instruments.

Analog To Digital Converters (ADC) Selection Notes

Select this component when high-speed multi-channel conversion is required with strict power constraints. The CTSD technology simplifies front-end design by removing the need for discrete sample-and-hold circuits. Compare performance against pipeline ADCs if lower latency is critical, noting that sigma-delta architectures typically introduce higher latency but offer superior noise shaping.
