MAX543BEPA

Digital To Analog Converters Overview

The MAX543BEPA is a 12-bit multiplying digital-to-analog converter (DAC) manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features an R-2R resistor ladder architecture and accepts serial data via a 3-wire interface. 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, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) 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 for through-hole mounting.

Digital To Analog Converters Feature Summary

• Multiplying DAC capability allows output scaling relative to an external reference voltage.
• CMOS construction ensures low power consumption suitable for battery-operated systems.
• Serial 3-wire interface minimizes pin count and simplifies system integration.
