ADC0834BCN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC0834BCN/NOPB is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a configurable input multiplexer with four single-ended or two differential analog channels. The device operates on a single 5 VDC supply and utilizes a TI MICROWIRE-compatible serial I/O interface for direct connection to microprocessors. Key electrical specifications include a maximum conversion time of 32 µs, a total unadjusted error of ±½ LSB, and low power consumption of 15 mW. It supports ratiometric operation or external voltage references within a 0V to 5V input range.

Analog To Digital Converters (ADC) Feature Summary

• Configurable 4-channel multiplexer supporting single-ended or differential input modes
• TI MICROWIRE compatible serial I/O interface for simplified processor integration
• 8-bit resolution with ±½ LSB total unadjusted error at 25°C
• Single 5VDC supply operation with 15 mW typical power dissipation

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring remote sensor data acquisition
• Microprocessor-based data logging and monitoring applications
• Battery-powered instrumentation utilizing ratiometric measurement techniques
• Automotive electronic control units operating in extended temperature ranges

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BCN' corresponds to the commercial temperature range (-40°C to +85°C) and SOIC-14 package as defined in the SNAS531B datasheet. Confirm that the NOPB designation indicates lead-free and RoHS compliance. Cross-reference the manufacturer's current production status, as legacy ADC families may have designated replacement parts available through official distributors.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with a 4-channel multiplexer is required for serial communication. Ensure the system clock frequency remains between 10 kHz and 400 kHz to meet timing specifications. Verify that the analog source impedance does not exceed 1 kΩ to prevent errors from multiplexer leakage currents. Consider the ADC0832-N if only two channels are needed, or the ADC0838-N for eight channels.

Analog To Digital Converters (ADC) Part Context

The ADC0834BCN/NOPB belongs to the ADC0831-N/ADC0832-N/ADC0834-N/ADC0838-N family of 8-bit serial A/D converters. This series provides software-configurable multiplexing options to handle various analog input configurations. The BCN variant specifically denotes the commercial temperature grade and surface-mount packaging, distinguishing it from the PDIP or PLCC package options available in the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers within the same functional family include the ADC0832CN/NOPB for 2-channel applications and the ADC0838CN/NOPB for 8-channel requirements. These devices share identical serial interfaces and pinouts where applicable, facilitating direct upgrades or channel count adjustments without redesigning the digital interface logic.
