ADC12081CIVT/NOPB

Analog To Digital Converters (ADC) Overview

The ADC12081CIVT/NOPB is a single-channel, 12-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a self-calibrating pipeline architecture to achieve a sampling rate of 5 MS/s. The device operates with both analog and digital supply voltages ranging from 4.75 V to 5.25 V. Key performance metrics include a signal-to-noise ratio of 68 dB and a signal-to-noise and distortion ratio of 67.6 dB. Linearity specifications feature a differential nonlinearity of 0.75 LSB and an integral nonlinearity of 1.7 LSB. It employs a parallel interface for data output and is housed in a 32-pin LQFP package.

Analog To Digital Converters (ADC) Feature Summary

• Integrates on-chip self-calibration circuitry to maintain accuracy without external trimming.
• Supports single-ended input configurations for simplified front-end design.
• Provides parallel digital output interface compatible with standard logic families.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring moderate speed and high resolution.
• Medical instrumentation such as ultrasound and patient monitoring devices.
• Test and measurement equipment including oscilloscopes and data acquisition modules.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix NOPB indicates lead-free and RoHS compliance status against current manufacturer documentation. Confirm the LQFP-32 package dimensions and pinout compatibility with your PCB footprint. Ensure power supply decoupling meets the requirements for the 4.75 V to 5.25 V operating range specified in the datasheet.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 12-bit resolution is required at speeds up to 5 MS/s. The pipeline architecture offers higher throughput than SAR types but consumes more power. Consider the parallel interface complexity versus serial alternatives if board space or pin count is constrained. Verify that the 68 dB SNR meets the dynamic range requirements of your application.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC12081 series of high-speed, low-power analog-to-digital converters. It is designed for applications needing a balance between resolution and speed. The CIVT/NOPB designation specifies the commercial temperature range, tape and reel packaging, and lead-free composition within the broader family of Texas Instruments data converters.

Analog To Digital Converters (ADC) Replacement Considerations

Check for direct pin-compatible upgrades within the same family, such as variants with different temperature grades or packaging options. Evaluate newer generations of pipeline ADCs for improved noise performance or lower power consumption if system constraints allow for redesign.
