MAX5380PEUK+T

Digital To Analog Converters Overview

The MAX5380PEUK+T is an 8-bit digital-to-analog converter (DAC) housed in a 5-pin SOT-23 package. It features a +2.0V internal reference and operates from a supply voltage range of +2.7V to +3.6V. The device utilizes a fast-mode I²C-compatible 2-wire serial interface with a preset slave address of 0x66. Key electrical parameters include a maximum supply current of 230µA, a shutdown mode current below 1µA, and an output settling time of 20µs. Integral nonlinearity (INL) and differential nonlinearity (DNL) are both specified at ±1 LSB maximum.

Digital To Analog Converters Feature Summary

• Includes an internal +2.0V reference eliminating the need for external components
• Features a buffered unity-gain follower output capable of driving resistive loads
• Provides software-controlled shutdown mode reducing power consumption significantly
• Integrates a low-glitch power-on reset circuit ensuring zero DAC output at startup

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to confirm pinout compatibility and factory-preset addressing. Ensure that the selected variant matches the required operating temperature range and supply voltage specifications for the target application environment.

Digital To Analog Converters Selection Notes

Select this component when space-constrained designs require an 8-bit resolution DAC within a miniature footprint. The fixed +2.0V internal reference dictates the maximum output swing; verify that this range aligns with downstream circuit requirements before finalizing the design.

Digital To Analog Converters Part Context

This part belongs to the MAX5380/MAX5381/MAX5382 family of low-cost, low-power DACs. The 'P' suffix indicates a specific factory-preset slave address of 0x66. Other variants in the series offer different internal references or wider supply ranges, but share the same physical package and core functionality.

Digital To Analog Converters Replacement Considerations

Compatible substitutes within the same family include MAX5380LEUK, MAX5380MEUK, and MAX5380NEUK. These alternatives share identical pinouts and performance characteristics but differ only in their factory-preset I²C slave addresses.
