MAX5815BAUD+

Digital To Analog Converters Overview

The MAX5815BAUD+ is a quad-channel, 12-bit voltage-output digital-to-analog converter (DAC) featuring buffered outputs and an internal reference. It operates on a wide analog supply range of 2.7V to 5.5V with a separate 1.8V to 5.5V digital I/O supply. The device utilizes a fast 400kHz I2C-compatible serial interface for control. Key electrical specifications include a typical settling time of 4.5µs, a maximum integral nonlinearity (INL) of ±1 LSB, and a differential nonlinearity (DNL) of ±0.2 LSB. Power consumption is extremely low at approximately 3mW. The component is housed in a compact 14-pin TSSOP package.

Digital To Analog Converters Feature Summary

• Four independent high-accuracy DAC channels with guaranteed monotonicity over all operating conditions
• Internal precision voltage reference selectable via software to 2.048V, 2.500V, or 4.096V
• Integrated output buffers enabling rail-to-rail operation and direct driving of loads up to 2kΩ
• Power-on-reset circuitry that initializes all DAC outputs to zero-scale upon startup

Digital To Analog Converters Applications

• Programmable Voltage and Current Sources
• Gain and Offset Adjustment Circuits
• Automatic Tuning and Optical Control Systems
• Process Control and Servo Loops

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'AUD+' against official documentation to confirm the package type and temperature grade. Ensure the host system supports the required 2.7V to 5.5V analog supply and 1.8V to 5.5V digital logic levels. Confirm that the 400kHz I2C clock rate aligns with the master controller's capabilities before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when four isolated 12-bit voltage outputs are required within a minimal footprint. The integrated buffer simplifies design by eliminating external amplifiers. Consider the separate VDDIO pin if the system requires level shifting between the analog domain and lower-voltage digital controllers. Verify thermal dissipation requirements given the 797mW power dissipation limit in the TSSOP package.

Digital To Analog Converters Part Context

This part belongs to the MAX581x family, which includes the MAX5813 (8-bit) and MAX5814 (10-bit). All variants share identical pinouts, interfaces, and physical dimensions. The primary distinction lies in resolution and linearity performance. This specific model provides the highest resolution within the series while maintaining the same ultra-small form factor and low-power characteristics.

Digital To Analog Converters Replacement Considerations

The MAX5813BAUD+ and MAX5814BAUD+ are pin-compatible alternatives offering 8-bit and 10-bit resolutions respectively. These may be used if higher precision is not required. No other cross-model replacements are confirmed in public documentation.
