MAX500ACWE+

Digital To Analog Converters Overview

The MAX500ACWE+ is a quad, 8-bit voltage-output digital-to-analog converter (DAC) in a 16-pin Wide SO package. It features four internally buffered output amplifiers and a cascadable serial interface compatible with TTL/CMOS logic. The device operates from single or dual supplies, with VDD ranging from +11.4V to +16.5V and VSS from -5V to 0V. Key electrical parameters include a maximum settling time of 4.5µs, ±1 LSB differential nonlinearity, and ±1 LSB total unadjusted error over the 0°C to +70°C operating temperature range.

Digital To Analog Converters Feature Summary

• Quad 8-bit DAC architecture with integrated unity-gain buffer amplifiers
• Cascadable 2-wire or 3-wire serial interface with double-buffered inputs
• Independent reference inputs for two channels; shared reference for the other two
• TTL and CMOS compatible digital logic levels without external adjustments

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'ACWE+' corresponds to the commercial temperature range (0°C to +70°C) and Wide SOIC-16 package. Confirm RoHS compliance status as indicated by the '+' suffix. Check current availability as this component may be subject to limited supply or end-of-life status depending on the distributor.

Digital To Analog Converters Selection Notes

Select the MAX500ACWE+ when four independent 8-bit outputs are required with minimal external components. Ensure the application supports the specified VDD range of +11.4V to +16.5V. For bipolar output configurations, external op-amps and resistors are necessary. Verify that the serial interface timing requirements align with the microprocessor or controller driving the SCL and SDA lines.

Digital To Analog Converters Part Context

The MAX500 series includes variants with different temperature ranges (-40°C to +85°C for 'E' suffix, -55°C to +125°C for 'M' suffix) and packages (Plastic DIP, CERDIP, LCC). The 'A' grade specifies tighter accuracy tolerances (±1 LSB INL/DNL) compared to the 'B' grade (±2 LSB). The ACWE+ variant specifically denotes the commercial grade in the 16-pin Wide SO package.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible replacements within the same family include MAX500BCWE+ (lower accuracy grade) or MAX500AEWE+ (extended temperature range). Cross-family replacements require verification of serial interface compatibility and output drive capabilities.
