MAX544ACSA+

Digital To Analog Converters Overview

The MAX544ACSA+ is a serial-input, voltage-output, 14-bit digital-to-analog converter (DAC) from Analog Devices Inc./Maxim Integrated. It operates from a single +5V supply and provides full 14-bit performance with ±0.5LSB INL and ±0.9LSB DNL over the commercial temperature range of 0°C to +70°C. The device features an unbuffered voltage output, resulting in low power consumption of 1.5mW and a supply current of 0.3mA. It utilizes a 10MHz, 3-wire serial interface compatible with SPI/QSPI/MICROWIRE standards. The DAC settles within 1µs for a full-scale step and includes a power-on reset circuit that clears the output to 0V in unipolar mode.

Digital To Analog Converters Feature Summary

• Full 14-bit linearity performance without adjustments
• Unbuffered voltage output capable of driving medium loads
• Power-on reset ensures zero-code output at startup
• Schmitt-trigger inputs allow direct optocoupler interfacing

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Industrial process control systems
• Automated test equipment
• Data-acquisition systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CSA' corresponds to the 8-pin SO package and commercial temperature range during procurement. Confirm RoHS compliance status as indicated by the '+' designation in the ordering information. Ensure the external reference voltage falls within the specified 2V to 3V range for optimal accuracy.

Digital To Analog Converters Selection Notes

Select this component when a single-supply, high-resolution DAC is required for unipolar applications. The unbuffered output architecture suits designs where low power consumption and minimal offset error are priorities. Verify that the load impedance exceeds 60kΩ to maintain specified linearity without an external buffer amplifier.

Digital To Analog Converters Part Context

The MAX544ACSA+ belongs to the MAX544/MAX545 family of 14-bit serial DACs. It serves as the 8-pin variant compared to the 14-pin MAX545, which offers additional bipolar operation capabilities via Kelvin-sense connections. This part is designed for cost-sensitive applications requiring precise analog control through a simple serial interface.

Digital To Analog Converters Replacement Considerations

Pin-compatible 16-bit upgrades such as the MAX541 or MAX542 are available if higher resolution is needed. For extended temperature ranges, consider the MAX544AEPA or MAX544BESA variants.
