MAX520ACPE+

Digital To Analog Converters Overview

The MAX520ACPE+ is a quad, 8-bit voltage-output digital-to-analog converter (DAC) from Analog Devices. It operates from a single +5V supply and features unbuffered outputs with rail-to-rail swing capability. The device utilizes a simple 2-wire serial interface compatible with I2C standards, supporting data rates up to 400kbps. Key electrical parameters include an operating temperature range of 0°C to +70°C, a maximum supply current of 10mA in normal operation, and 4µA in power-down mode. Differential nonlinearity is specified at ±1 LSB, while integral nonlinearity is ±1.5 LSB.

Digital To Analog Converters Feature Summary

• Quad 8-bit DAC architecture with individual reference inputs for each channel
• Unbuffered voltage outputs providing ultra-low supply current consumption
• I2C-compatible 2-wire serial interface allowing multiple devices on one bus
• Power-on reset ensures DAC outputs initialize to 0V upon power application

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific package variant, as the MAX520 series includes DIP, SO, and SSOP options. Confirm that the 'A' grade designation indicates factory-trimmed output resistance accuracy. Check for RoHS compliance status relative to manufacturing date codes. Ensure the design supports the required slave address configuration via AD pins.

Digital To Analog Converters Selection Notes

Select the MAX520ACPE+ when low power consumption is critical, as its unbuffered outputs draw significantly less current than buffered alternatives like the MAX521. This part is suitable for applications requiring separate reference voltages per channel. Consider the 16-pin PDIP package constraints regarding board space and thermal dissipation capabilities during system integration.

Digital To Analog Converters Part Context

This component belongs to the MAX520/MAX521 family of quad and octal serial DACs manufactured by Maxim Integrated, now part of Analog Devices. The MAX520 specifically denotes the quad-channel version with unbuffered outputs, distinguishing it from the octal MAX521 which includes internal buffer amplifiers. The AC suffix indicates commercial temperature range performance.

Digital To Analog Converters Replacement Considerations

Direct replacement options include other members of the MAX520 family such as the MAX520BCPE+ or variants in different packages like the MAX520ACWE+. Verify pin compatibility and electrical specifications before substitution, particularly regarding output drive capability and reference input requirements.
