MAX521BEAG+

Digital To Analog Converters Overview

The MAX521BEAG+ is an octal, 8-bit voltage-output digital-to-analog converter with rail-to-rail buffered outputs. It operates from a single +5V supply and features a 2-wire serial interface compatible with I2C protocols. The device supports data rates up to 400kbps and includes individual reference inputs for each DAC channel. Key electrical parameters include an 8-bit resolution, 6µs settling time, and a maximum supply current of 24mA in normal operation.

Digital To Analog Converters Feature Summary

• Octal configuration with eight independent 8-bit DAC channels
• Rail-to-rail buffered voltage outputs for direct load driving
• I2C-compatible 2-wire serial interface with programmable slave addresses
• Individual reference inputs allow independent full-scale control per channel

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Industrial process control systems
• Automatic test equipment signal generation
• Programmable attenuators and threshold adjustments

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BEAG+' against official Analog Devices documentation to confirm temperature range and package type. Confirm RoHS compliance status as manufacturing practices may vary by production era. Check for obsolescence notices or lifecycle changes on the manufacturer website before design finalization.

Digital To Analog Converters Selection Notes

Select this component when multiple isolated analog outputs are required from a single controller. The buffered outputs simplify PCB layout by eliminating external op-amps. Ensure the system power supply remains stable at +5V, as the reference input range includes the supply rails. Verify that the I2C bus speed does not exceed 400kHz.

Digital To Analog Converters Part Context

This part belongs to the MAX520/MAX521 family of quad and octal DACs. While the MAX520 offers unbuffered outputs for lower power consumption, the MAX521 variant provides integrated buffer amplifiers. The BEAG+ designation indicates a specific grade and packaging option within this legacy Maxim Integrated product line, now managed by Analog Devices.

Digital To Analog Converters Replacement Considerations

Direct pin-for-pin replacements must maintain the octal 8-bit architecture and I2C interface. Verify that substitute devices support the same +5V supply voltage and rail-to-rail output swing. Check if alternative parts offer improved linearity specifications or extended industrial temperature ranges if the current application demands higher precision.
