ADC12DC080CISQE/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12DC080 is a dual-channel, 12-bit analog-to-digital converter operating at sampling rates up to 80 MSPS. It utilizes a differential pipelined architecture with digital error correction and an on-chip sample-and-hold circuit. The device features a full-power bandwidth of 1 GHz and operates from a single +3.0V supply. Key dynamic specifications include a typical Signal-to-Noise Ratio (SNR) of 69.5 dBFS and a Spurious Free Dynamic Range (SFDR) of 83 dBFS at an input frequency of 170 MHz. Power consumption is typically 600 mW during full operation.

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix /NOPB, which indicates lead-free status. Confirm the package type is the 60-lead WQFN (9x9x0.8mm). Ensure the operating temperature range matches the industrial specification of -40°C to +85°C. Check that the source document corresponds to Texas Instruments SNAS405C datasheet for accurate electrical limits.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel high-speed digitization is required within a single package. It is suitable for applications needing a 1 GHz full-power bandwidth and CMOS-compatible digital outputs. Consider the 7-cycle conversion latency and 4.7 ns minimum output delay when designing clocking and data capture logic. Ensure the system can provide a stable 1.5V common mode voltage via the VCMO pins.
