MX7543JN

Digital To Analog Converters Overview

The MX7543JN is a CMOS, 12-bit serial-input Digital-to-Analog Converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes an R-2R resistor ladder architecture to convert digital data into analog current outputs. The device features a serial interface for data input and requires an external voltage reference. It operates on dual 5V supplies for analog and digital sections. Key electrical specifications include a settling time of 2µs, a maximum integral nonlinearity (INL) of ±1 LSB, and a differential nonlinearity (DNL) of ±2 LSB. The component is housed in a 16-pin PDIP package and supports binary or offset binary input codes.

Digital To Analog Converters Procurement Notes

Verify the specific suffix designation against the manufacturer's official datasheet to confirm exact performance grades and temperature ranges. Ensure compatibility with existing serial communication protocols used in the target system design. Check for RoHS compliance status if environmental regulations apply to the final assembly. Confirm package dimensions match the intended PCB footprint layout constraints.

Digital To Analog Converters Selection Notes

Select this component when a 12-bit resolution is sufficient for the application's accuracy requirements. Consider the serial interface capability if parallel pins are limited on the microcontroller. Evaluate the 2µs settling time against the required update rate of the analog output. Verify that the external reference voltage matches the desired full-scale output range of the DAC circuit.
