ADS574JH

Analog To Digital Converters (ADC) Overview

The ADS574JH is a microprocessor-compatible sampling CMOS analog-to-digital converter manufactured by Texas Instruments. It features an 8-bit resolution and operates with a single +5V power supply. The device utilizes a high-speed successive approximation architecture to achieve conversion times of 10 microseconds at 100 kSPS or 20 microseconds at 50 kSPS. It includes an internal reference voltage source and a sample-and-hold amplifier, reducing external component requirements. The input range is selectable between 0-5V and 0-10V. Designed for direct interface with standard microprocessors, it supports both parallel and multiplexed data bus configurations.

Analog To Digital Converters (ADC) Feature Summary

• 8-bit resolution with 100 kSPS (10 µs) or 50 kSPS (20 µs) conversion rates
• Single +5V power supply operation with internal reference and sample-and-hold
• Selectable input voltage ranges: 0-5V or 0-10V
• Microprocessor-compatible parallel interface supporting multiplexed data buses

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring analog signal digitization
• Data acquisition systems for sensor interfacing
• Portable battery-powered instrumentation due to low power consumption
• Automotive test equipment and monitoring applications

Analog To Digital Converters (ADC) Part Context

The ADS574 series belongs to Burr-Brown's family of microprocessor-compatible ADCs acquired by Texas Instruments. These devices were designed to simplify system design by integrating essential functions like the sample-and-hold and reference into a single package. The 'JH' suffix typically denotes a ceramic dual in-line package (CDIP) variant suitable for industrial or military temperature ranges, distinguishing it from plastic package versions like the 'PC' or 'N' variants.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-for-pin replacements within the same family include the ADS574PC (plastic DIP) or ADS574N. For upgraded performance, newer generations such as the ADS7844 or ADS8364 may be considered, though these often require interface adjustments due to differences in resolution, speed, or communication protocols.
