MAX543ACPA+

Digital To Analog Converters Overview

The MAX543ACPA+ is a single-channel, 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an R-2R resistor ladder architecture and features a serial 3-wire interface for data input. The device operates with analog and digital supply voltages ranging from 5 V to 15 V. Key performance specifications include a settling time of 250 ns, a differential nonlinearity (DNL) of ±0.5 LSB, and an integral nonlinearity (INL) of ±0.5 LSB. It draws a typical operating current of 5 µA and dissipates up to 727 mW. The component is housed in an 8-pin PDIP package and supports through-hole mounting.

Digital To Analog Converters Feature Summary

• Multiplying capability allows the DAC output to scale proportionally with the external reference voltage.
• CMOS construction ensures low power consumption suitable for battery-operated or energy-efficient systems.
• External reference input provides flexibility for custom voltage range configurations.

Digital To Analog Converters Applications

• Programmable gain amplifiers requiring precise attenuation or amplification factors.
• Battery-powered instrumentation where low quiescent current is critical.
• Industrial control systems utilizing serial communication buses.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'PA+' indicates lead-free compliance and RoHS adherence before procurement. Confirm that the 3-wire serial protocol matches the host controller's interface capabilities. Ensure the external reference voltage source meets the required accuracy to maintain the specified linearity performance. Check for any obsolescence notices as this component may be subject to limited availability.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, high-resolution voltage-output DAC is not required, but rather a current-output multiplying function. Compare against the MAX543BCWE+ if surface-mount packaging is preferred over through-hole. Consider the MAX543AMJA for extended industrial temperature ranges if operation below 0°C or above 70°C is necessary. Evaluate power dissipation limits relative to the ambient thermal environment.

Digital To Analog Converters Part Context

This part belongs to the MAX543A series of CMOS multiplying DACs. It shares architectural similarities with other Maxim Integrated serial DACs but is distinct in its 12-bit resolution and specific 3-wire interface timing. The 'A' grade denotes standard linearity specifications compared to higher precision variants.

Digital To Analog Converters Replacement Considerations

The MAX543BCWE+ offers identical electrical characteristics in a surface-mount SOIC-8 package. For military-grade temperature ranges, the MAX543AMJA is the direct functional equivalent in a ceramic DIP package. Verify pin compatibility when substituting between package types.
