MAX525AEPP

Digital To Analog Converters Overview

The MAX525AEPP+ is a low-power, quad, 12-bit voltage-output digital-to-analog converter (DAC) with a serial interface. It integrates four DACs and precision output amplifiers in a 20-pin Plastic DIP package. The device operates on a single +5V supply with typical normal operation current of 0.85mA and shutdown current of 10µA. Key electrical parameters include a settling time of 12µs to ±1/2LSB, an INL of ±0.5LSB, and DNL of ±1LSB. It supports SPI/QSPI and MICROWIRE interfaces.

Digital To Analog Converters Feature Summary

• Integrates four 12-bit DACs with configurable output amplifiers
• Features software shutdown and hardware shutdown lockout for low power consumption
• Includes active-low reset to clear all registers and DACs to zero
• Supports simultaneous or independent control via 3-wire serial interface

Digital To Analog Converters Applications

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'EPP+' against the manufacturer's official datasheet to confirm the extended temperature range (-40°C to +85°C) and PDIP-20 packaging. Confirm RoHS compliance status as indicated in the component documentation. Check for obsolescence notices, as this series may be subject to discontinuation by Analog Devices/Maxim Integrated.

Digital To Analog Converters Selection Notes

Select the MAX525AEPP+ when a quad-channel, 12-bit resolution is required with buffered voltage outputs. Ensure the application environment falls within the -40°C to +85°C operating range. Verify that the system power supply is stable at +5V ±10%. Consider the external reference requirement and available serial interface compatibility (SPI/MICROWIRE) before finalizing the design.

Digital To Analog Converters Part Context

This component belongs to the MAX525 family of low-power, quad, 12-bit voltage-output DACs manufactured by Analog Devices Inc./Maxim Integrated. The family includes variants with different temperature ranges and packages, such as the BC grade for commercial temperatures and SSOP packages. The AEPP+ variant specifically denotes the industrial temperature range and plastic DIP packaging.

Digital To Analog Converters Replacement Considerations

Public confirmed substitutes are not explicitly listed in the provided source material. Users should consult the manufacturer's official documentation for any officially recommended replacement parts or updated components within the MAX525 family line.

Digital To Analog Converters FAQ

How does the MAX525 handle data updates?

Each DAC has a double-buffered input consisting of an input register and a DAC register. Data can be loaded into the input registers without affecting the DAC registers, allowing for independent or simultaneous updates of all four DACs through the serial interface.

What is the function of the PDL pin?

The Power-Down Lockout (PDL) pin disables software shutdown when held low. Transitioning PDL from high to low while in shutdown mode wakes up the part, restoring the output state to what it was prior to entering shutdown.

Can the MAX525 be daisy-chained?

Yes, any number of MAX525 devices can be daisy-chained by connecting the DOUT pin of one device to the DIN pin of the next. This allows multiple units to be controlled using a common serial interface bus.
