MAX275ACPP+

Overview

The MAX275ACPP+ is a low-power, quad, 12-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices / Maxim Integrated. It features a serial interface compatible with SPI, QSPI, Microwire, and standard 3-wire protocols. The device utilizes an R-2R resistor ladder architecture to provide buffered voltage outputs. It operates on a single 5V analog and digital supply, consuming only 850µA of operating current. Key performance metrics include a settling time of 12µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±0.5 LSB. The reference voltage range spans from 0V to 4.1V. It is housed in a 20-pin PDIP package and functions within a commercial temperature range of 0°C to +70°C.

Feature Summary

• Integrates four independent 12-bit DAC channels with internal buffering for direct drive capability.
• Supports flexible serial communication through compatibility with multiple industry-standard interfaces including SPI and Microwire.
• Designed for ultra-low power consumption suitable for battery-operated or portable applications.

Applications

• Portable instrumentation requiring multi-channel signal generation
• Battery-powered test and measurement equipment
• Process control systems with serial bus connectivity

Procurement Notes

Verify component authenticity through authorized distributors or the manufacturer directly. Confirm RoHS compliance status and check for end-of-life notices as availability may be restricted. Ensure the specific AC grade temperature rating matches your environmental requirements before finalizing procurement.

Selection Notes

Select this component when a quad-channel configuration is required to minimize board space compared to discrete single-channel solutions. The 12-bit resolution and ±0.5 LSB INL make it suitable for moderate precision applications. Verify that the 5V supply voltage aligns with your system architecture and that the serial interface timing meets your microcontroller's specifications.

Part Context

This part belongs to the MAX274/MAX275 family of low-power DACs. The MAX274 variant offers two channels, while the MAX275 provides four. Both share identical electrical characteristics and pinouts, differing primarily in channel count. The 'AC' suffix denotes the commercial temperature range, and 'PP+' indicates the lead-free PDIP packaging.

Replacement Considerations

Direct functional substitutes within the same family include the MAX274ACPP+ for dual-channel applications. Cross-vendor replacements require matching 12-bit resolution, quad-channel count, and serial interface compatibility. Verify pinout alignment and supply voltage requirements before substitution.
