ADC0808CCV/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0808CCV/NOPB is an 8-bit analog-to-digital converter utilizing Successive Approximation Register (SAR) architecture. It features an integrated 8-channel multiplexer with single-ended input configuration. The device operates on a single 4.5 V to 6.5 V power supply and supports a sampling rate of 10 ksps. It provides parallel digital output via three-state buffers for direct microprocessor interfacing. The component is housed in a 28-pin PLCC surface-mount package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 8-channel analog multiplexer with address decoding logic
• Parallel data output interface compatible with standard microprocessors
• Single-supply operation capability simplifying system design

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for environmental monitoring
• Embedded measurement instruments

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCV' against the manufacturer's current product status, as the base ADC0808 series has undergone lifecycle changes. Confirm RoHS compliance documentation matches the NOPB designation. Ensure the PLCC-28 package availability aligns with current manufacturing capabilities, as older packages may be subject to discontinuation notices.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the application. The internal multiplexer reduces external switching requirements compared to devices without integrated MUX. Consider the PLCC package constraints for PCB layout if higher pin counts or smaller footprints are required in future revisions.

Analog To Digital Converters (ADC) Part Context

This part belongs to the Texas Instruments ADC080x family, which includes the ADC0808 and ADC0809. The ADC0808 is functionally similar to the ADC0809 but lacks the START trigger input, relying instead on internal timing or external control for conversion initiation. It serves as a legacy solution for basic 8-bit conversion tasks.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitutes include the ADC0808CCN/NOPB (DIP-28 variant) and the ADC0808CCV (non-NOPB version). Verify pin compatibility and electrical specifications before substitution, particularly regarding the absence of the START pin in the ADC0808 compared to the ADC0809.
