MAX5812PEUT-T

Digital To Analog Converters Overview

The MAX5812PEUT-T is a single-channel, 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc./Maxim Integrated. It features a voltage-output architecture with an I2C-compatible 2-wire serial interface supporting clock rates up to 400kHz. The device operates on a single supply voltage ranging from 2.7V to 5.5V, drawing 100µA at 3.6V and 130µA at 5.5V. Key electrical parameters include a settling time of 4µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±2 LSB. It utilizes a resistor-string structure and includes a rail-to-rail output buffer. The component is housed in a miniature 6-pin SOT-23 package and supports power-down modes with selectable impedances.

Digital To Analog Converters Feature Summary

• Ultra-low power consumption with active current draw under 130µA and low-power shutdown mode below 1µA
• Integrated rail-to-rail output buffer amplifier for direct signal driving capabilities
• Software-selectable power-down output impedances including high impedance, 1kΩ, and 100kΩ options
• Built-in power-on reset circuit ensuring the DAC initializes to zero state upon startup

Digital To Analog Converters Applications

• Digital gain and offset adjustments in signal processing chains
• Programmable voltage and current sources for sensor biasing
• Battery-operated equipment requiring minimal quiescent current
• Low-cost instrumentation systems utilizing I2C connectivity

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'PEUT' against official manufacturer documentation, as standard listings typically utilize 'LEUT' or 'MEUT'. Confirm RoHS compliance status and lead times directly with authorized distributors. Ensure the ordering code matches the exact temperature range and packaging requirements specified in the final datasheet revision.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, 12-bit resolution is required alongside strict power constraints. The I2C interface simplifies system design by reducing pin count compared to parallel DACs. Consider the 4µs settling time for application speed requirements. Verify that the SOT-23-6 package fits the available PCB real estate and thermal management strategy.

Digital To Analog Converters Part Context

The MAX5812 belongs to the Maxim Integrated family of low-power, serial digital-to-analog converters. It shares architectural similarities with the MAX5811 but offers higher 12-bit resolution. This series is designed for applications where space and power efficiency are critical, leveraging a compact SOT-23 footprint while maintaining precision through internal calibration and buffering.

Digital To Analog Converters Replacement Considerations

The MAX5811 serves as a compatible alternative if 10-bit resolution is sufficient for the application. Both devices share identical pinouts, interfaces, and power characteristics, facilitating drop-in replacements within existing designs without schematic modifications.
