ADC0809CCV/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0809CCV/NOPB is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It integrates an 8-channel multiplexer and operates with a single 5 V supply. The device features a parallel digital interface and utilizes a 28-pin PLCC surface-mount package. Key electrical parameters include a sampling rate of 10 ksps, an input voltage range of 0 to 5 V, and a typical power dissipation of 15 mW. It functions within a temperature range of -40°C to +85°C and requires an external clock signal for operation.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel analog multiplexer for multi-point signal acquisition
• Microprocessor-compatible parallel output with TTL-level three-state buffers
• Successive Approximation Register (SAR) architecture for efficient conversion
• Single-supply operation compatible with standard logic families

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel sensor monitoring
• Data acquisition modules for environmental or physical parameter logging
• Embedded instrumentation interfaces for low-speed analog signal digitization
• Educational microcontroller development platforms for ADC principles

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCV' confirms the PLCC-28 surface-mount package variant rather than DIP. Confirm RoHS compliance status as indicated by the '/NOPB' designation against current regulatory requirements. Validate that the manufacturer lists this part as active or obsolete, as availability may be limited. Ensure the supplier provides genuine Texas Instruments components to avoid counterfeit risks associated with legacy parts.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 10 ksps throughput are sufficient for the application. It is suitable for designs requiring direct integration of an 8-channel multiplexer without external switching components. Consider the PLCC package constraints for PCB layout if surface mounting is required. Evaluate alternative SAR ADCs if higher speed or differential input capabilities are necessary.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC0808/ADC0809 family of 8-bit A/D converters originally developed by National Semiconductor and now produced by Texas Instruments. It is functionally pin-compatible with the ADC0808 but offers lower input leakage current in the multiplexer stage. The NOPB suffix indicates a lead-free and RoHS-compliant manufacturing version of the original plastic leaded chip carrier package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADS8528SRGCR is listed as a manufacturer-recommended replacement for the ADC0809CCV/NOPB. Verify compatibility regarding package type, pinout, and performance specifications before substitution.
