MAX538BCPA

Digital To Analog Converters Overview

The MAX538BCPA+ is a low-power, voltage-output, 12-bit digital-to-analog converter (DAC) designed for single +5V supply operation. It features a serial interface compatible with SPI, QSPI, and Microwire standards. The device draws only 140µA of supply current and includes a power-on reset circuit. Key electrical specifications include a settling time of 25µs to ±1/2 LSB, integral nonlinearity (INL) of ±0.5 LSB maximum, and differential nonlinearity (DNL) of ±1 LSB. The output buffer is fixed at a gain of +1, providing a unipolar output range from 0V to VDD. It operates within a temperature range of 0°C to +70°C and is housed in an 8-pin PDIP package.

Digital To Analog Converters Feature Summary

• Low-power consumption with 140µA supply current
• Integrated buffered voltage output with fixed +1 gain
• Serial data output capability for daisy-chaining multiple devices
• Guaranteed monotonic performance over the operating temperature range

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the component authenticity by checking the manufacturer marking against the official datasheet pinout and physical dimensions. Confirm the ordering suffix matches the required temperature grade and packaging style. Ensure the supplier provides valid traceability documentation. Cross-reference the part number with the latest Analog Devices product change notices to confirm availability status and any potential obsolescence warnings before finalizing procurement.

Digital To Analog Converters Selection Notes

Select this component when a single-supply 12-bit DAC with low power consumption is required. It is suitable for applications needing a buffered voltage output without external amplification. Consider the MAX531 if an internal reference or bipolar operation is needed, or the MAX539 if a gain of +2 is desired. Ensure the system interface supports the three-wire serial protocol and that the 25µs settling time meets the application's speed requirements.

Digital To Analog Converters Part Context

The MAX538 belongs to the MAX531/MAX538/MAX539 family of low-power, voltage-output, serial 12-bit DACs. These devices are specified for single +5V power-supply operation. The MAX538 differs from the MAX531 by lacking an internal reference and configurable amplifier, and from the MAX539 by having a fixed unity-gain buffer instead of a gain-of-two buffer. All parts in this series are trimmed for offset voltage, gain, and linearity.

Digital To Analog Converters Replacement Considerations

The MAX538BCPD+ is a surface-mount equivalent in an SOIC-8 package. For dual-supply or internal reference needs, consider the MAX531BCPA+. If a higher gain output is required, the MAX539BCPA+ is a direct functional alternative with a gain of +2.
