MAX538ACSA+

Digital To Analog Converters Overview

The MAX538ACSA+ is a low-power, voltage-output, 12-bit digital-to-analog converter (DAC) specified for single +5V power-supply operation. It features a serial interface compatible with SPI, QSPI, and Microwire standards. The device draws only 140µA of supply current and includes an internal reference. Key electrical parameters include a resolution of 12 bits, a settling time of 25µs to ±1/2 LSB, and integral nonlinearity (INL) of ±1 LSB maximum. The output buffer is fixed at a gain of +1, providing unipolar output ranges from 0V to VDD or 0V to 2.6V. Operating temperature range is 0°C to +70°C.

Digital To Analog Converters Feature Summary

• Low-power consumption with 140µA supply current
• Internal 2.048V reference for simplified design
• Guaranteed monotonic performance over temperature
• Flexible unipolar output voltage ranges

Digital To Analog Converters Applications

• Battery-powered test instruments
• Digital offset and gain adjustment circuits
• Battery-operated remote industrial controls
• Machine and motion control devices

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CSA+' against official Analog Devices documentation to confirm package type and lead-free status. Ensure compatibility with required operating temperature ranges and supply voltages before procurement. Cross-reference part numbers with authorized distributors to avoid counterfeit components.

Digital To Analog Converters Selection Notes

Select the MAX538ACSA+ when a single-channel, 12-bit DAC with low power consumption is required. It is suitable for applications needing a fixed +1 gain buffer and internal reference. Compare with MAX539 if a +2 gain buffer is needed, or MAX531 if bipolar operation or external reference flexibility is required.

Digital To Analog Converters Part Context

The MAX538ACSA+ belongs to the MAX531/MAX538/MAX539 family of low-power, voltage-output DACs. These devices are designed for single +5V supply operation and feature serial interfaces. The MAX538 specifically offers a fixed +1 gain buffer and internal reference, distinguishing it from the MAX539 (+2 gain) and MAX531 (configurable gain/bipolar).

Digital To Analog Converters Replacement Considerations

MAX538AEPA+ is a pin-compatible through-hole alternative in the same series. Verify that the replacement matches the required package style and temperature grade.
