ADS574AU

Analog To Digital Converters (ADC) Overview

The ADS574AU is a microprocessor-compatible, sampling CMOS analog-to-digital converter manufactured by Burr-Brown (Texas Instruments). It features a 12-bit resolution and operates with a single +5V digital supply and dual ±10V to ±15V analog supplies. The device utilizes a successive approximation architecture with a throughput rate of 1 MSPS. Key electrical parameters include a maximum conversion time of 3 µs and a typical input voltage range of ±10V. It is housed in a 28-pin plastic DIP package and supports parallel data output.

Analog To Digital Converters (ADC) Feature Summary

• 12-bit resolution with 1 MSPS sampling rate
• Microprocessor-compatible interface requiring minimal control logic
• Single +5V digital power supply with ±10V to ±15V analog supplies
• Internal clock and reference for simplified system design

Analog To Digital Converters (ADC) Applications

• Industrial process control systems
• Data acquisition modules
• Medical instrumentation
• Test and measurement equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the manufacturer origin, as Burr-Brown was acquired by Texas Instruments. Confirm the specific suffix 'AU' corresponds to the plastic DIP package and commercial temperature range in the official datasheet. Check for obsolescence status or lifecycle notifications from the current manufacturer before procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a 12-bit SAR ADC with a 1 MSPS speed is required. Ensure the system can accommodate the dual analog supply rails (±10V to ±15V) and the single +5V digital rail. Compare against newer successors like the ADS774 series if lower power or higher speeds are needed.

Analog To Digital Converters (ADC) Part Context

The ADS574AU belongs to the Burr-Brown family of microprocessor-compatible ADCs. This series was designed to simplify interfacing with standard logic families by integrating internal clocks and references, reducing the external component count compared to earlier generation converters.

Analog To Digital Converters (ADC) Replacement Considerations

Consult the Texas Instruments replacement guide for the ADS574. Potential functional equivalents may include the ADS774AU or ADS774H, which offer similar interfaces but potentially improved performance metrics. Verify pin compatibility and electrical specifications before substitution.
