MAX520BCPE+

Digital To Analog Converters Overview

The MAX520BCPE+ is a quad, 8-bit voltage-output digital-to-analog converter with a 2-wire serial interface. It operates from a single +5V supply and features unbuffered outputs for ultra-low power consumption of 4µA. The device supports data rates up to 400kbps and includes individual reference inputs for each DAC channel. Key electrical parameters include an operating temperature range of 0°C to +70°C, a resolution of 8 bits, and a settling time of 2µs.

Digital To Analog Converters Feature Summary

• Quad-channel 8-bit architecture with independent reference inputs
• Ultra-low 4µA supply current in normal operation
• I2C-compatible 2-wire serial interface supporting up to 400kbps
• Power-on reset ensures outputs start at 0V

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCPE+' against the manufacturer's official datasheet to confirm the package type (16-pin Plastic DIP) and temperature grade (Commercial, 0°C to +70°C). Ensure the design requires unbuffered outputs, as this variant differs from buffered versions. Confirm availability through authorized distributors, as lead times may vary based on production status.

Digital To Analog Converters Selection Notes

Select this component when low power consumption is critical, as the unbuffered outputs draw only 4µA compared to higher currents in buffered variants. Choose this part over the MAX521 if rail-to-rail buffering is not required and minimal quiescent current is prioritized. Ensure the application can accommodate the external reference input requirements and the 16-pin DIP footprint constraints.

Digital To Analog Converters Part Context

This device belongs to the MAX520/MAX521 family of quad/octal 8-bit DACs manufactured by Analog Devices/Maxim Integrated. It is designed for applications requiring simple serial control and low power. The MAX520 specifically provides unbuffered outputs to minimize supply current, distinguishing it from the buffered MAX521 series within the same product line.

Digital To Analog Converters Replacement Considerations

Direct replacements include other MAX520 variants with different packages or temperature grades, such as MAX520ACWE+ or MAX520AEWE+. Verify that substitute parts maintain the unbuffered output configuration and compatible I2C interface timing specifications.
