MAX520BEAP+

Digital To Analog Converters Overview

The MAX520BEAP+ is a quad, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and features unbuffered outputs with rail-to-rail swing. The device utilizes a simple 2-wire serial interface compatible with I2C systems, supporting data rates up to 400kbps. Key electrical parameters include an 8-bit resolution, ±1 LSB differential nonlinearity (DNL), and ±1 LSB integral nonlinearity (INL). The typical output settling time is 2µs, and the supply current is ultra-low at 4µA in normal operation.

Digital To Analog Converters Feature Summary

• Quad-channel 8-bit DAC architecture with unbuffered voltage outputs
• I2C-compatible 2-wire serial interface for simplified system integration
• Ultra-low power consumption with 4µA supply current and dedicated shutdown mode
• Individual reference inputs for each DAC channel allowing independent scaling

Digital To Analog Converters Applications

• Minimum component analog systems
• Digital offset and gain adjustment circuits
• Industrial process control instrumentation
• Automatic test equipment (ATE)
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the specific package type associated with the BEAP suffix against official Analog Devices documentation, as standard listings often cite SOIC or DIP packages. Confirm that the component meets RoHS3 compliance requirements for your assembly process. Ensure the source provides valid traceability for this discontinued or legacy part number, as availability may be limited compared to active series members.

Digital To Analog Converters Selection Notes

Select the MAX520BEAP+ when a quad-channel solution with unbuffered outputs is required to minimize supply current. This part is suitable for applications where the load impedance is high enough to avoid buffering needs. Compare it against the MAX521 if buffered outputs are necessary for driving lower impedance loads. Consider the external reference requirement, as this device does not include an internal reference generator.

Digital To Analog Converters Part Context

This component belongs to the MAX520/MAX521 family of quad/octal, 2-wire serial 8-bit DACs. The MAX520 variant specifically provides four channels with unbuffered outputs, distinguishing it from the MAX521 which offers eight buffered channels. The family is designed for low-power, space-constrained applications requiring simple serial communication protocols.

Digital To Analog Converters Replacement Considerations

Direct replacements include other variants within the MAX520 family such as MAX520ACPE or MAX520BCWE depending on the required package and temperature range. Verify pin compatibility and electrical specifications before substitution. No cross-family replacements are confirmed in the provided documentation.
