ADC12020CIVY

Analog To Digital Converters (ADC) Overview

The ADC12020CIVY is a single-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It operates at a sampling rate of 20MSPS and utilizes a proprietary pipeline architecture with digital error correction. The device features an on-chip sample-and-hold circuit and accepts differential analog inputs. It functions on a single +5V supply, consuming 185mW at full speed, with power reducing to 40mW in shutdown mode. The output format is offset binary, compatible with 2.35V to 5V logic levels. It is housed in a 32-pin LQFP package and supports an industrial operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix to confirm package type and RoHS compliance status. The base part number indicates a standard commercial or industrial grade variant. Confirm lead times and availability directly with authorized distributors as inventory levels fluctuate. Ensure the procurement documentation matches the exact pinout and electrical specifications required for the target design.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate-speed, 12-bit resolution is sufficient for the application. It is suitable for designs requiring low power consumption and a single 5V supply rail. Consider the ADC12010 or ADC12040 if different sampling rates are needed, as they share pin compatibility. Evaluate the ENOB performance at the specific input frequency to ensure it meets system dynamic range requirements.

Analog To Digital Converters (ADC) Part Context

This device belongs to the Texas Instruments ADC120xx family of high-speed analog-to-digital converters. The family shares common architectural features such as pipeline conversion and digital error correction. Variants within the series typically differ in sampling speed, such as the ADC12010 (10MSPS) or ADC12040 (40MSPS), while maintaining similar pinouts and power characteristics.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC12010 and ADC12040 are pin-compatible alternatives offering lower and higher sampling rates, respectively. Verify that the specific voltage levels and power constraints of the new part align with the existing board design before substitution.
