ADC0838CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0838CIWMX/NOPB is an 8-bit analog-to-digital converter manufactured by Texas Instruments. It features a serial input/output interface and supports up to eight single-ended or four differential input channels via an integrated multiplexer. The device operates on a single power supply ranging from 4.5 V to 6.3 V, with a typical sampling rate of 31.2 kSPS. It includes an internal reference voltage source and track-and-hold circuitry. The component is housed in a 20-pin SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates an 8-channel multiplexer with track-and-hold functionality for efficient multi-point signal acquisition.
• Features a built-in internal reference voltage source to simplify external circuit design.
• Utilizes a serial interface compatible with standard microcontroller communication protocols.

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel data acquisition.
• Battery-powered instrumentation utilizing low-voltage operation.
• Portable measurement devices needing compact surface-mount packaging.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'NOPB' confirms RoHS compliance and lead-free construction as per Texas Instruments standards. Confirm the 'X' designation indicates reel packaging rather than tube. Ensure the operating environment remains within the specified -40°C to +85°C industrial temperature range to maintain performance specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and moderate speed are sufficient for the application. Consider the internal reference capability if external precision references are undesirable. Verify that the serial interface timing requirements align with the host microcontroller's capabilities. Evaluate the 20-SOIC footprint against available PCB space constraints.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC08xx family of high-speed, low-power analog-to-digital converters. It serves as a successor to earlier parallel-interface models, offering reduced pin count through serial communication. The device bridges the gap between simple parallel ADCs and complex high-speed serial converters.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0838CIWM/NOPB (tube package) is a direct functional equivalent differing only in packaging format. Other members of the ADC08xx series may offer different channel counts or resolutions but require interface verification.
