MAX500AEWE

Digital To Analog Converters Overview

The MAX500AEWE is a quad, 8-bit voltage-output digital-to-analog converter (DAC) housed in a 16-pin Wide SO package. It features a cascadable serial interface and four internally buffered output amplifiers. The device operates from single or dual supplies, with VDD ranging from +11.4V to +16.5V and VSS from -5V to 0V. It achieves 8-bit performance over the full operating temperature range (-40°C to +85°C) without external trimming. The DACs utilize inverted R-2R ladder networks, allowing for simultaneous updates via double-buffered logic and a 10-bit shift register.

Digital To Analog Converters Feature Summary

• Quad 8-bit DACs with buffered voltage outputs
• Two- or three-wire cascadable serial interface
• Double-buffered digital inputs for simultaneous updates
• Three reference inputs allowing independent range setting for two DACs

Digital To Analog Converters Applications

• Minimum component count analog systems
• Digital offset/gain adjustment
• Industrial process control
• Arbitrary function generators
• Automatic test equipment

Digital To Analog Converters Procurement Notes

Verify the specific suffix AEWE indicates the -40°C to +85°C temperature range and 16-pin Wide SO package. Confirm RoHS compliance status as the datasheet does not explicitly state it for this part number. Check for obsolescence status through official Analog Devices channels, as older Maxim Integrated parts may have limited availability.

Digital To Analog Converters Selection Notes

Select the MAX500AEWE when four independent 8-bit DAC channels are required with serial control. Ensure the application supports the specified supply voltages (VDD +11.4V to +16.5V). Consider the reference input impedance characteristics, which vary with code, requiring low-impedance reference sources (≤20Ω). Verify that the serial interface timing meets the microprocessor or controller requirements.

Digital To Analog Converters Part Context

The MAX500 series includes variants with different temperature ranges and packages. The 'A' grade specifies ±1 LSB total unadjusted error, while 'B' grade specifies ±2 LSB. The 'E' suffix denotes the extended temperature range of -40°C to +85°C. The 'W' suffix indicates the 16-pin Wide SOIC package. Other options include Plastic DIP (P), CERDIP (J), and LCC (L) packages.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include MAX500BEWE (±2 LSB accuracy) or MAX500ACWE (commercial temperature range). For different packages, MAX500AEPE offers the same electrical specifications in a 16-pin Plastic DIP. Cross-family replacements require careful evaluation of interface compatibility and performance parameters.
