MAX525BEPP

Digital To Analog Converters Overview

The MAX525BEPP+ is a low-power, quad, 12-bit voltage-output digital-to-analog converter (DAC) with serial interface. It integrates four DACs and precision output amplifiers in a 20-pin PDIP package. The device operates on a single +5V supply with typical current consumption of 0.85mA in normal mode and 10µA in shutdown. Key electrical parameters include a settling time of 12µs to ±1/2LSB, integral nonlinearity of ±1LSB, and differential nonlinearity of ±1LSB. It supports SPI/QSPI and MICROWIRE interfaces.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to the commercial grade. Confirm the 'P' suffix denotes the Plastic DIP package style. Ensure RoHS compliance status matches current manufacturing standards. Check for availability as this component may be subject to lifecycle changes or obsolescence notices from Analog Devices.

Digital To Analog Converters Selection Notes

Select the MAX525BEPP+ when four independent 12-bit voltage outputs are required in a single package. Choose this part over single-channel DACs to save board space. Consider the external reference requirement if precise full-scale accuracy is needed. Verify that the serial interface timing meets the microprocessor clock requirements. Ensure the operating temperature range aligns with the system environment.

Digital To Analog Converters Part Context

The MAX525 belongs to the Maxim Integrated data converter family, designed for applications requiring multiple analog outputs controlled via serial communication. It replaces older parallel-interface DACs by reducing pin count and simplifying PCB layout. The device is suitable for systems needing moderate speed and high resolution with low power consumption.

Digital To Analog Converters Replacement Considerations

Direct replacements must match the quad 12-bit architecture and serial interface compatibility. Verify pin-out compatibility for the 20-pin PDIP package. Check if alternative parts offer similar settling times and linearity specifications. Ensure the replacement supports the same supply voltage and shutdown current requirements.

Digital To Analog Converters FAQ

How does the MAX525 handle simultaneous updates of all DAC channels?

All four DAC registers can be updated simultaneously from their respective input registers using a single software command through the 3-wire serial interface.

What is the function of the Power-Down Lockout (PDL) pin?

The PDL pin disables software shutdown when held low. Transitioning PDL from high to low while in shutdown wakes up the part, restoring the output state prior to shutdown.

Can the MAX525 be daisy-chained with other devices?

Yes, any number of MAX525s can be daisy-chained by connecting the DOUT pin of one device to the DIN pin of the next device in the chain.
