MAX503CWG

Digital To Analog Converters Overview

The MAX503CWG+ is a low-power, 10-bit voltage-output digital-to-analog converter (DAC) in a 24-pin Wide SO package. It operates from single +5V or dual ±5V supplies with typical supply currents of 250µA and 40µA in shutdown mode. The device integrates a laser-trimmed 2.048V internal reference and an output buffer amplifier. Key electrical specifications include a relative accuracy (INL) of ±0.5 LSB max, differential nonlinearity (DNL) of ±1 LSB max, and a settling time of 25µs to 0.01%. It features double-buffered parallel logic inputs compatible with 4-bit, 8-bit, and 16-bit microprocessors.

Digital To Analog Converters Feature Summary

• Integrated 2.048V laser-trimmed voltage reference and buffered op-amp output
• Low power consumption: 250µA operating current (single supply), 40µA shutdown current
• Double-buffered parallel interface for 4-bit, 8-bit, and 16-bit microprocessor compatibility
• Configurable output ranges: 0V to +2.048V, 0V to +4.096V, or ±2.048V via ROFS pin

Digital To Analog Converters Applications

• Battery-powered data-conversion products
• Industrial process control systems
• Arbitrary function generators
• Automatic test equipment
• Microprocessor-controlled calibration

Digital To Analog Converters Procurement Notes

Verify the ordering suffix 'WG+' indicates the 24-pin Wide SOIC package and commercial temperature range (0°C to +70°C). Confirm RoHS compliance status as indicated by the '+' suffix. Check manufacturer documentation for lead-free soldering profiles and moisture sensitivity levels prior to assembly.

Digital To Analog Converters Selection Notes

Select this component for applications requiring minimal external components due to the integrated reference and buffer. Ensure the parallel interface timing requirements (setup/hold times) match the host microprocessor capabilities. For higher resolution needs, consider the software-compatible MAX530. Verify that the load capacitance does not exceed stability limits for the output buffer.

Digital To Analog Converters Part Context

The MAX503 is part of Maxim Integrated's low-power DAC family. The 'C' suffix denotes the commercial temperature range (0°C to +70°C), while 'E' variants cover -40°C to +85°C. The 'WG' suffix specifies the 24-pin Wide Small Outline package. This model serves as a hardware and software compatible predecessor to the 12-bit MAX530.

Digital To Analog Converters Replacement Considerations

Direct substitutes include other MAX503 variants with different packages (e.g., MAX503CNG for DIP, MAX503CAG for SSOP) or temperature ranges (MAX503EWG). For 12-bit upgrades, the MAX530 offers pin-compatible functionality with increased resolution.
