MAX535ACUA+

Digital To Analog Converters Overview

The MAX535ACUA+ is a low-power, 13-bit voltage-output digital-to-analog converter (DAC) with a precision output amplifier in an 8-pin µMAX package. It operates from a single +5V supply and draws 280µA of supply current. The device features a double-buffered input register and DAC register accessed via a 3-wire serial interface compatible with SPI/QSPI or Microwire. Key electrical parameters include a resolution of 13 bits, a typical settling time of 16µs to ±1/2LSB, and INL/DNL specifications of ±0.5/±1 LSB respectively. The operating temperature range is 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Integrates a 13-bit R-2R ladder DAC with a buffered output amplifier in a compact 8-pin µMAX package.
• Features a software-programmable shutdown mode that reduces supply current to approximately 4µA while retaining register data.
• Includes Schmitt-trigger digital inputs for direct interfacing with optocouplers without additional buffering.
• Provides access to the output amplifier's inverting input, allowing users to configure gain, remote sensing, or high output current capabilities.

Digital To Analog Converters Applications

• Industrial process control systems
• Automatic test equipment
• Digital offset and gain adjustment circuits
• Motion control applications
• Microprocessor-controlled systems

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'CUA+' corresponds to the 8-pin µMAX package and commercial temperature grade when sourcing. Confirm RoHS compliance status as indicated on the manufacturer's official documentation. Check for availability constraints or obsolescence notices directly from Analog Devices or authorized distributors before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select the MAX535ACUA+ for designs requiring a single +5V supply and 13-bit resolution. Ensure the application supports the 0°C to +70°C operating temperature range. Verify that the serial interface timing requirements align with the host microcontroller's SPI or Microwire configuration. Consider the external reference voltage requirements and load conditions to maintain specified linearity performance.

Digital To Analog Converters Part Context

This component belongs to the MAX535/MAX5351 family of low-power, 13-bit voltage-output DACs. The MAX535 variant specifically targets +5V single-supply operation, whereas the MAX5351 variant is designed for +3.3V supplies. Both share identical pinouts and functional architectures, differing primarily in supply voltage ranges and associated electrical characteristics.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same series include MAX535BCUA+ for standard accuracy or MAX535BEUA+ for extended temperature ranges. Cross-family alternatives may require schematic adjustments due to differences in supply voltage, interface protocols, or package dimensions.
