ADC0834CCWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0834CCWMX/NOPB is an 8-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and features a serial interface compatible with Microwire and SPI protocols. The device includes an onboard multiplexer supporting two differential or four single-ended input channels. It operates on a single 5 V supply, with both analog and digital power pins connected to the same voltage source. The component is housed in a 14-pin SOIC-Wide package and supports surface-mount installation. It provides a sampling rate of 31 kS/s and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated multiplexer allows flexible configuration for either two differential or four single-ended analog inputs.
• Serial communication interface ensures compatibility with standard microprocessor control lines and reduces pin count requirements.
• Onboard reference eliminates the need for external voltage reference components, simplifying circuit design.

Analog To Digital Converters (ADC) Applications

• Battery-powered instrumentation systems requiring low pin-count connectivity.
• Industrial process control loops utilizing thermocouple or RTD sensors.
• Data acquisition modules for environmental monitoring applications.

Analog To Digital Converters (ADC) Procurement Notes

Verify that the suffix /NOPB confirms lead-free construction and RoHS compliance prior to ordering. Confirm the CCWMX designation indicates the specific wide-body SOIC-14 tape-and-reel packaging variant. Ensure the selected distributor sources directly from Texas Instruments or authorized channels to guarantee authenticity and traceability of the semiconductor material.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 31 kS/s throughput are sufficient for the application. Choose this part over parallel ADCs if board space is limited and fewer I/O pins are available. Consider alternative models if higher resolution or faster conversion speeds are required for the specific signal processing needs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC083x family of 8-bit serial A/D converters. It shares architectural similarities with the ADC0832 and ADC0831 but distinguishes itself through the inclusion of a built-in multiplexer. This integration allows for multiple channel selection without external switching hardware, differentiating it from single-channel counterparts in the same series.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC0834CCWM/NOPB serves as a direct non-rohs predecessor. Verify pinout compatibility before substitution. Other family members like the ADC0832 lack the multiplexer feature and require different system configurations.
