ADC0820CCWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0820CCWM/NOPB is an 8-bit analog-to-digital converter manufactured by Texas Instruments, formerly National Semiconductor. It utilizes a Successive Approximation Register (SAR) architecture with a single-ended input type and parallel interface. The device operates on a 5 V supply for both analog and digital domains, achieving a sampling rate of 666 kS/s. It features tri-state outputs compatible with MOS and TTL voltage levels. The component is housed in a 20-lead SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with SAR structure

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor. Confirm the suffix /NOPB indicates lead-free compliance. Ensure the package matches the SOIC-20 specification and check humidity sensitivity handling requirements during storage and assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and parallel interface are required for moderate-speed applications up to 666 kS/s. It is suitable for designs needing direct interfacing with TTL or CMOS logic without additional level shifting. Consider power consumption of 65 mW and the need for an external reference voltage.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0820 series, representing high-speed, low-power 8-bit A/D converters. The NOPB suffix denotes non-halogenated and lead-free construction, aligning with RoHS standards. It serves as a bridge between legacy National Semiconductor products and current Texas Instruments portfolios.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC0820CCW. Verify if the specific suffix variations affect electrical parameters or packaging before substitution.
