MAX5217GUA+

Digital To Analog Converters Overview

The MAX5217GUA+ is a single-channel, 16-bit digital-to-analog converter with a buffered voltage output and I2C interface. It operates from a 2.7V to 5.5V supply with a maximum supply current of 80µA. The device features rail-to-rail output capability driven by an external reference input ranging from 2V to VDD. Integral nonlinearity is typically 1.2 LSB and maximally 4 LSB. Differential nonlinearity is typically 0.25 LSB and maximally 1 LSB. The offset error is typically 0.25mV with a maximum of 1.25mV. Settling time to ±0.5 LSB is 18µs.

Digital To Analog Converters Procurement Notes

Verify the component is sourced from authorized distributors to ensure authenticity. Confirm the suffix GUA+ indicates the µMAX package and lead-free status as per Maxim Integrated specifications. Check for RoHS compliance documentation if required for specific regulatory standards. Ensure the ordering part number matches the exact pin configuration and electrical characteristics needed for the design.

Digital To Analog Converters Selection Notes

Select the MAX5217 when 16-bit accuracy is required alongside low power constraints. The buffered output simplifies driving loads without external amplifiers. Consider the external reference input for flexibility in setting output ranges. The I2C interface reduces pin count compared to parallel DACs. Evaluate the AUX pin functionality if asynchronous hardware control of the DAC state is necessary for system safety.

Digital To Analog Converters Part Context

This component belongs to the MAX5215/MAX5217 family of low-power, buffered output DACs. The MAX5217 provides 16-bit resolution, while the pin-compatible MAX5215 offers 14-bit resolution. Both share identical interfaces and power characteristics. The series is designed for applications demanding high precision in compact packages with minimal power draw.

Digital To Analog Converters Replacement Considerations

The MAX5215 serves as a lower-resolution alternative within the same package and interface family. Verify that any substitute maintains the 2.7V to 5.5V supply range and I2C compatibility. Ensure the replacement supports the required 16-bit linearity specifications if accuracy is critical. Check thermal resistance values to confirm adequate heat dissipation in the target application environment.
