MAX528CAG+

Digital To Analog Converters Overview

The MAX528CAG+ is an octal, 8-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features a serial interface compatible with standard SPI protocols and includes integrated output buffers for each channel. The device operates within an analog supply voltage range of 10.8V to 16.5V and a negative supply range of -1.5V to -5.5V, while the digital supply matches the analog upper limit. Key performance specifications include a settling time of 3µs, integral nonlinearity (INL) of ±0.3 LSB, and differential nonlinearity (DNL) of ±0.3 LSB. It utilizes an R-2R architecture and is housed in a 24-SSOP package.

Digital To Analog Converters Feature Summary

• Integrated voltage output buffers on all channels
• Serial data interface supporting standard communication protocols
• High precision linearity with low INL and DNL errors

Digital To Analog Converters Applications

• Multi-channel signal generation systems
• Industrial process control instrumentation
• Programmable power supply designs
• Data acquisition front-end conditioning

Digital To Analog Converters Procurement Notes

Verify the suffix designation carefully during procurement. The plus sign (+) indicates compliance with current environmental standards, distinguishing it from older non-compliant variants. Confirm package integrity upon receipt, as the SSOP form factor requires specific handling precautions to maintain pin alignment and solder joint quality during assembly processes.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. Ensure the system power rails accommodate the specified wide voltage ranges for both analog and digital sections. Verify that the serial interface timing requirements align with the host microcontroller's clock speeds to guarantee reliable data transfer without setup or hold time violations.

Digital To Analog Converters Part Context

This part belongs to the MAX528 family of high-density DACs designed for applications requiring multiple precise analog outputs. It serves as the lead-free, RoHS-compliant successor to earlier versions like the MAX528CAG. The device shares architectural similarities with the MAX529 but differs primarily in packaging options and specific supply voltage tolerances defined by the manufacturer.

Digital To Analog Converters Replacement Considerations

The MAX528CAG+ is the direct lead-free replacement for the discontinued MAX528CAG. Both components share identical electrical characteristics and pinouts, allowing for drop-in substitution in existing designs without circuit modification.
