MAX275AEPP

Overview

The MAX275AEPP+ is a low-power, quad, 12-bit voltage-output digital-to-analog converter (DAC) featuring a serial interface. It operates on a single +5V supply with an analog supply range of 4.75V to 5.5V and a digital supply range of 2.7V to 5.5V. The device provides four buffered voltage outputs and supports 3-Wire, Microwire, QSPI, and SPI interfaces. It achieves a settling time of 12µs and offers integral nonlinearity of ±0.5 LSB and differential nonlinearity of ±1 LSB. Operating temperatures range from -40°C to +85°C in a 20-pin PDIP package.

Feature Summary

• Integrates four independent 12-bit DAC channels with internal output buffers for direct drive capability.
• Supports multiple standard serial communication protocols including SPI, QSPI, Microwire, and 3-wire interfaces.
• Operates efficiently on a single +5V power supply, reducing system complexity and component count.

Applications

• Portable instrumentation systems requiring multi-channel signal generation
• Battery-powered test equipment utilizing single-supply operation
• Industrial process control loops needing precise voltage referencing

Procurement Notes

Verify the specific suffix 'A' indicates the extended temperature grade (-40°C to +85°C). Confirm the '+' suffix denotes lead-free and RoHS compliance status according to current manufacturer documentation. Check availability as this series may be subject to discontinuation or lifecycle changes.

Selection Notes

Select the MAX275 over the MAX274 when four independent output channels are required instead of two. Ensure the serial interface timing matches the host controller's SPI or Microwire configuration. Verify that the 12-bit resolution and 12µs settling time meet the application's accuracy and speed requirements.

Part Context

This component belongs to the MAX274/MAX275 family of low-power, quad/dual 12-bit DACs. It shares architectural similarities with other Maxim Integrated serial DACs but is distinct in its specific channel count and voltage output buffering capabilities designed for general-purpose data acquisition tasks.

Replacement Considerations

The MAX274AEPP+ serves as a dual-channel alternative within the same family. Cross-reference with newer generations of serial DACs if long-term supply assurance is critical, ensuring pinout and register compatibility are maintained during migration.
