MAX518BESA

Digital To Analog Converters Overview

The MAX518BESA is an 8-bit dual voltage-output digital-to-analog converter featuring a 2-wire serial interface. It operates from a single +5V supply with internal precision buffers enabling rail-to-rail output swing. The device uses the supply voltage as the reference for both DACs and supports data rates up to 400kbps. A low-power shutdown mode reduces supply current to 4µA, while power-on reset ensures outputs are at 0V upon initial application of power.

Digital To Analog Converters Feature Summary

• Dual 8-bit DACs with rail-to-rail buffered outputs
• Simple 2-wire serial interface compatible with I2C
• Uses supply voltage as internal reference
• Low-power shutdown mode reducing current to 4µA

Digital To Analog Converters Applications

• Digital offset and gain adjustment
• Industrial process control systems
• Automatic test equipment
• Programmable attenuators

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'E' indicates the extended temperature range (-40°C to +85°C) compared to commercial variants. Confirm package type is SO-8. Check for RoHS compliance status on current manufacturing lots. Ensure the source document explicitly lists this part number as available or discontinued before procurement planning.

Digital To Analog Converters Selection Notes

Select the MAX518 when two independent analog outputs are required from a single component. Choose this over the MAX517 if dual channels are needed, or the MAX519 if external reference inputs per channel are necessary. The MAX518 is suitable for applications where the supply voltage serves as a stable reference and space-saving 8-pin packaging is preferred.

Digital To Analog Converters Part Context

The MAX518 belongs to the MAX517/MAX518/MAX519 family of 8-bit voltage-output DACs manufactured by Analog Devices Inc./Maxim Integrated. These devices share a common serial interface protocol and architectural design, differing primarily in channel count and reference input configurations. The MAX518 specifically provides dual channels with a fixed supply-referenced architecture.

Digital To Analog Converters Replacement Considerations

The MAX517 and MAX519 are pin-compatible members of the same family but offer different channel counts and reference options. Verify that the system does not require external reference inputs (MAX519) or only a single channel (MAX517). No other direct public substitutes are confirmed in the provided documentation.
