MAX521BCAG

Digital To Analog Converters Overview

The MAX521BCAG is an octal, 8-bit voltage-output digital-to-analog converter featuring rail-to-rail buffered outputs. It operates from a single +5V supply and utilizes a simple 2-wire serial interface compatible with I2C protocols. The device supports data rates up to 400kbps and includes individual reference inputs for each channel. Key electrical parameters include an operating temperature range of 0°C to +70°C, a typical settling time of 6µs, 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
• Individual reference inputs allow flexible gain and offset adjustments per channel
• Integrated power-on reset ensures outputs initialize to 0V

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Automatic test equipment for programmable stimulus sources
• Digital offset and gain adjustment circuits
• Programmable attenuators in communication infrastructure

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCAG' against the manufacturer's official ordering guide, as package and temperature codes define physical form factors. Confirm RoHS compliance status for the specific revision, as legacy Maxim Integrated parts may have varying environmental certifications. Ensure the design accounts for the SOIC-24 or SSOP-24 footprint depending on the exact package variant indicated by the suffix.

Digital To Analog Converters Selection Notes

Select this component when an octal DAC architecture is required with minimal external components due to integrated output buffers. It is suitable for designs needing simultaneous updates across multiple channels via double-buffered registers. Consider the MAX520 if unbuffered outputs and lower quiescent current are prioritized over drive capability. Verify that the 2-wire serial interface timing meets the system controller's SCL frequency requirements.

Digital To Analog Converters Part Context

This part belongs to the MAX520/MAX521 family of quad and octal 8-bit DACs manufactured by Analog Devices (formerly Maxim Integrated). The MAX521 variant specifically distinguishes itself through buffered outputs, whereas the MAX520 offers unbuffered outputs for ultra-low power applications. This family is designed for cost-sensitive, space-constrained analog systems requiring reliable digital-to-analog conversion.

Digital To Analog Converters Replacement Considerations

Direct replacements include other members of the MAX521 series with different temperature grades or packaging options, such as MAX521ACWG+ or MAX521BEPP+. Verify pin compatibility and electrical specifications before substitution. Note that the original Maxim Integrated brand has been acquired by Analog Devices, so support and documentation are now managed through ADI channels.
