MAX5841LEUB+

Digital To Analog Converters Overview

The MAX5841LEUB+ is a quad, 10-bit voltage-output digital-to-analog converter (DAC) featuring an I2C-compatible 2-wire serial interface. It operates from a single 2.7V to 5.5V supply and draws 230µA at VDD = 3.6V. The device includes internal precision rail-to-rail output buffers and a power-on reset circuit that initializes the DAC to zero scale in 100kΩ power-down mode. It supports three software-selectable power-down output impedances: 100kΩ, 1kΩ, and high impedance. The part is specified over an extended temperature range of -40°C to +85°C and is housed in a 10-pin µMAX package.

Digital To Analog Converters Feature Summary

• Quad 10-bit resolution with segmented resistor string architecture ensuring monotonicity
• Ultra-low power consumption with 230µA active current and <1µA power-down current
• I2C/SMBus compatible 2-wire serial interface with Schmitt-trigger inputs for direct interfacing
• Internal precision rail-to-rail unity-gain output buffers

Digital To Analog Converters Applications

• Digital gain and offset adjustments
• Programmable voltage and current sources
• Programmable attenuation circuits
• VCO and varactor diode control
• Battery-powered equipment

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'LEUB+' corresponds to the required address configuration and package type. Confirm the manufacturer is Analog Devices Inc./Maxim Integrated. Ensure the component meets RoHS3 compliance standards as indicated in official documentation. Check for any specific environmental or export classification requirements relevant to your region.

Digital To Analog Converters Selection Notes

Select this component when a low-power, quad-channel DAC with I2C connectivity is required. It is suitable for applications needing rail-to-rail output swing and software-configurable power-down states. Consider the 10-pin µMAX package constraints and the need for external pull-up resistors on the SDA and SCL lines for proper bus operation.

Digital To Analog Converters Part Context

The MAX5841 belongs to a family of low-power serial DACs from Maxim Integrated. The 'L' suffix indicates a factory-programmed slave address where the ADD pin is connected to GND. This distinguishes it from the 'M' variant, which sets the ADD pin to VDD. Both variants share identical electrical characteristics and functionality within the same package.

Digital To Analog Converters Replacement Considerations

Refer to the MAX5842 data sheet for the 12-bit version of this device. Other quad DACs may require different interface protocols or power supplies. Verify pin compatibility and register mapping before substituting with similar parts from other manufacturers.
