MAX515EPA

Digital To Analog Converters Overview

The MAX515EPA is a low-power, voltage-output, 10-bit digital-to-analog converter (DAC) specified for single +5V power-supply operation. It features a fixed gain of 2 buffer amplifier and draws only 140µA of supply current. The device utilizes an inverted R-2R ladder network with a CMOS op amp to convert 10-bit digital data to analog voltage levels. It operates within a temperature range of -40°C to +85°C and is housed in an 8-pin Plastic DIP package.

Digital To Analog Converters Feature Summary

• Low-power operation with 140µA supply current
• Fixed gain of 2 buffered voltage output
• Guaranteed monotonic performance over temperature
• Power-on reset ensures DAC outputs are at zero scale

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to the 'C' variant (0°C to +70°C). Confirm the package type matches the required 8-pin Plastic DIP form factor. Ensure compatibility with single +5V supply requirements as the device is not designed for dual supplies.

Digital To Analog Converters Selection Notes

Select the MAX515EPA when a fixed gain of 2 is required for the voltage output. Unlike the MAX504, this device lacks an internal reference and configurable gain, making it suitable for designs where external references are preferred or gain flexibility is unnecessary. It offers hardware and software compatibility with 12-bit upgrades like the MAX531/MAX538/MAX539.

Digital To Analog Converters Part Context

The MAX515 belongs to the Maxim Integrated family of low-power, serial 10-bit DACs. It shares architectural similarities with the MAX504 but differs in pin count and feature set, specifically lacking the internal reference and programmable gain amplifier found in the 14-pin MAX504. This simplifies the design for applications requiring a straightforward, fixed-gain voltage output.

Digital To Analog Converters Replacement Considerations

The MAX504 serves as a functional alternative if internal reference and configurable gain are needed, though it requires a 14-pin package. For higher resolution needs, the MAX531, MAX538, or MAX539 provide a 12-bit upgrade path with hardware and software compatibility.
