MAX5380MEUK+T

Digital To Analog Converters Overview

The MAX5380MEUK+T is an 8-bit digital-to-analog converter (DAC) housed in a 5-pin SOT-23 package. It features a fast-mode I²C-compatible serial interface supporting data rates up to 400kbps and includes four factory-preset slave addresses, with the 'M' suffix designating address 0x62. The device operates from a +2.7V to +3.6V supply and incorporates an internal +2V reference. Key electrical parameters include a maximum supply current of 230µA, a shutdown mode reducing current to less than 1µA, and a power-on reset ensuring zero output at startup. Integral nonlinearity (INL) and differential nonlinearity (DNL) are guaranteed within ±1 LSB.

Digital To Analog Converters Feature Summary

• Integrates an internal +2V voltage reference for simplified system design
• Features a buffered voltage output capable of driving resistive loads
• Includes a software-controlled shutdown mode that pulls the output to ground via an internal resistor
• Provides low-glitch power-on reset to ensure DAC outputs remain at zero during initial power application

Digital To Analog Converters Applications

• Automatic tuning for Voltage-Controlled Oscillators (VCO)
• Power-amplifier bias control circuits
• Programmable threshold level adjustment
• Automatic gain control systems
• Automatic offset adjustment mechanisms

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the preset slave address and temperature range. Ensure the component meets RoHS compliance requirements for your assembly process. Confirm availability through authorized distributors as stock levels fluctuate. Cross-reference the datasheet revision date to validate the accuracy of the electrical specifications provided.

Digital To Analog Converters Selection Notes

Select this component when a miniature footprint and low power consumption are critical constraints. The MAX5380 is suitable for single-supply applications requiring an internal reference. Verify that the required supply voltage falls within the +2.7V to +3.6V operating range. Consider the fixed +2V reference limitation if higher output voltages are necessary for the target application.

Digital To Analog Converters Part Context

This part belongs to the MAX5380/MAX5381/MAX5382 family of low-cost, low-power 8-bit DACs. The series shares identical pinouts and core functionality but differs in internal reference voltages and supply voltage ranges. The MAX5380 specifically targets lower voltage applications with its integrated +2V reference, distinguishing it from the MAX5381 and MAX5382 variants.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the MAX5380LEUK+T, MAX5380NEUK+T, and MAX5380PEUK+T. These alternatives share the same package and electrical characteristics but utilize different factory-preset slave addresses (0x60, 0x64, and 0x66 respectively). Ensure the system's I²C addressing scheme accommodates any changes in the slave address.
