ADC0832CCWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0832CCWM/NOPB is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments, originally part of the National Semiconductor portfolio. It features a serial I/O interface compliant with the NSC MICROWIRE standard and includes a configurable input multiplexer supporting up to two channels in this specific package configuration. The device operates on a single 5V supply (4.5V to 6.3V range) with a sampling rate of 31 kS/s. It supports both differential and single-ended input types, eliminating the need for zero or full-scale adjustment. The component is housed in a 14-pin SOIC-Wide surface-mount package and functions within an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit SAR architecture with 31 kS/s sampling rate
• MICROWIRE-compatible serial I/O interface
• Configurable 2-channel multiplexer for single-ended or differential inputs
• Single 5V power supply operation without external reference requirement

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring serial communication
• Battery-powered devices due to low power consumption
• Microprocessor-based data acquisition systems
• Ratiometric sensor interfaces

Analog To Digital Converters (ADC) Procurement Notes

Verify that the manufacturer designation reflects Texas Instruments, as National Semiconductor was acquired by TI. Confirm the suffix /NOPB indicates lead-free and RoHS compliance. Ensure the package matches the SOIC-14 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 serial interface are required for space-constrained designs. The SOIC-14 package suits surface-mount applications. Consider the 31 kS/s speed limit and 5V operating voltage constraints. Verify channel count requirements, as other variants in the series may support more channels.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC0832-N family, which also includes ADC0831, ADC0834, and ADC0838. These devices share similar architectures but differ in channel counts and specific interface configurations. The ADC0832 specifically offers dual-channel multiplexing capabilities suitable for multi-sensor applications.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible substitutes include ADC0832CCN/NOPB (DIP package) and ADC0832CIMX/NOPB (SOIC-8 package). Cross-reference with ADC0831 or ADC0834 if channel count differences are acceptable. Verify electrical parameters match before substitution.
