ADC12040CIVY

Analog To Digital Converters (ADC) Overview

The ADC12040CIVY is a monolithic CMOS analog-to-digital converter featuring a 12-bit resolution and a pipeline architecture. It supports a minimum sampling rate of 40 MSPS with an internal sample-and-hold circuit. The device operates on a single +5V supply, consuming 340 mW at full speed, while the digital interface is compatible with voltages from 2.35 V to 5 V. Key electrical specifications include a signal-to-noise ratio (SNR) of 70 dB, differential nonlinearity (DNL) of +/- 0.4 LSB, and integral nonlinearity (INL) of 1.8 LSB. It utilizes a differential input type and provides parallel output data in 12-bit offset binary format within a 32-lead LQFP package.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix against the manufacturer's current datasheet, as ordering codes often include packaging or temperature variations. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the component matches the required 32-lead LQFP package dimensions and pinout configuration for your PCB layout.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution and 40 MSPS throughput are required with low power consumption. Consider the ADC12040CIVY if a single +5V analog supply and flexible digital voltage range (2.35V–5V) are necessary. Evaluate the 70 dB SNR and differential input requirements against system noise budgets before finalizing the design.
