ADS7824UBG4

Analog To Digital Converters (ADC) Overview

The ADS7824UBG4 is a 12-bit, 4-channel analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and operates with a single-ended input configuration. The device supports both parallel and SPI serial interfaces for data output. It functions within an analog and digital supply voltage range of 4.75 V to 5.25 V. Key performance metrics include a sampling rate of 40 kS/s, a maximum conversion time of 21 µs, and a power dissipation of 50 mW. The unit is housed in a 28-pin SOIC package and offers internal or external reference options.

Analog To Digital Converters (ADC) Feature Summary

• Supports flexible data interface configurations via parallel or SPI modes
• Integrates selectable internal or external voltage reference capabilities
• Provides high-resolution 12-bit conversion accuracy across four channels

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for sensor interfacing
• Portable instrumentation utilizing low-power ADC solutions

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'BG4' indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the package type matches the required PCB footprint for the 28-pin SOIC variant. Ensure the operating environment stays within the specified -40°C to +85°C temperature range. Check for moisture sensitivity level requirements during storage and handling procedures before assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit resolution with four single-ended inputs is required. It is suitable for applications needing either parallel or serial communication protocols. Consider the 40 kS/s sampling rate against system bandwidth needs. Evaluate the 50 mW power consumption against battery life constraints if used in portable designs.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADS7824 series of CMOS sampling analog-to-digital converters. It shares architectural similarities with other devices in the family but differs in channel count and interface options compared to variants like the ADS7844 or ADS7808. The UBG4 designation specifies the industrial temperature grade and lead-free packaging format.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes may include other 12-bit, 4-channel SAR ADCs from Texas Instruments such as the ADS7824PG4, which offers the same functionality in a DIP package. Cross-vendor replacements require matching resolution, channel count, and interface compatibility.
