MAX5382MEUK+T

Digital To Analog Converters Overview

The MAX5382MEUK+T is an 8-bit digital-to-analog converter (DAC) housed in a 5-pin SOT-23 package. It operates from a supply voltage range of +2.7V to +5.5V and features an internal reference voltage equal to 0.9 x VDD. The device utilizes a fast-mode I²C-compatible 2-wire serial interface supporting data rates up to 400kbps. Key electrical specifications 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 guaranteed at ±1 LSB, with a full-scale error of less than ±5%.

Digital To Analog Converters Feature Summary

• Integrated buffered voltage output capable of driving resistive loads.
• Software-controlled low-power shutdown mode reducing supply current to under 1µA.
• Power-on reset circuit ensures DAC outputs initialize to zero upon power application.
• I²C-compatible serial interface allows communication with multiple devices using preset slave addresses.

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix MEUK corresponds to the required factory-preset slave address (0x62) and temperature range (-40°C to +85°C). Confirm that the internal reference characteristic of 0.9 x VDD aligns with the system's voltage requirements. Ensure compatibility with the host microcontroller's I²C logic levels and bus timing constraints before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a wide supply voltage range (+2.7V to +5.5V) is required compared to the fixed-voltage variants in the series. The MAX5382 is suitable for designs needing an internal reference derived directly from the supply rail rather than fixed external references. Verify that the 8-bit resolution and <±5% full-scale error meet the application's accuracy needs.

Digital To Analog Converters Part Context

The MAX5382 belongs to the MAX5380/MAX5381/MAX5382 family of low-cost, low-power 8-bit DACs. While sharing the same SOT-23-5 package and serial interface, it differs from the MAX5380 and MAX5381 by operating over the full +2.7V to +5.5V range with a supply-dependent internal reference. This distinguishes it from the MAX5380 (+2V ref) and MAX5381 (+4V ref), which have narrower supply ranges.

Digital To Analog Converters Replacement Considerations

Direct functional substitutes within the same package and interface include other MAX5382 variants with different preset addresses (MAX5382LEUK, MAX5382NEUK, MAX5382PEUK). Cross-family replacements like the MAX5383 offer similar performance but utilize a 3-wire serial interface instead of the 2-wire I²C-compatible bus.
