MAX520AEWE+

Digital To Analog Converters Overview

The MAX520AEWE+ is a quad, 8-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and features an unbuffered voltage output architecture that reduces total supply current to 4µA while providing increased accuracy at low output currents. The device utilizes a simple 2-wire serial interface compatible with I2C systems, allowing communication at data rates up to 400kbps. It includes individual reference inputs for each DAC channel and supports simultaneous or individual register updates via double-buffered input configuration.

• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range of -40°C to +85°C compared to the commercial 'C' grade. Confirm the package type matches the wide SOIC-16 specification. Ensure the ordering code corresponds to the lead-free (+) designation as per manufacturer standards. Cross-reference the datasheet revision to confirm pinout compatibility with existing designs.

Digital To Analog Converters Selection Notes

Select the MAX520AEWE+ when unbuffered outputs are acceptable to minimize power consumption and component count. This part is suitable for applications requiring low output currents where high accuracy is maintained without buffering. Choose this over the MAX521 if rail-to-rail buffered outputs are not required. Verify that the system can accommodate the external reference voltage requirements specified in the electrical characteristics.

Digital To Analog Converters Part Context

The MAX520 belongs to a family of quad and octal 8-bit DACs designed for low-power, space-constrained applications. The AEWE+ variant specifically denotes the extended temperature grade housed in a 16-pin wide SOIC package. This series emphasizes simplicity through its 2-wire interface, reducing microprocessor port usage. It serves as a cost-effective solution for multi-channel signal generation in industrial and consumer electronics.

Digital To Analog Converters Replacement Considerations

Direct replacement options include other variants within the MAX520/MAX521 family, such as the MAX520ACWE+ for commercial temperature ranges. Ensure any substitute maintains the same 8-bit resolution, serial interface protocol, and +5V supply requirement. Verify thermal performance matches the extended temperature specifications if operating in harsh environments.
