MAX518BCPA

Digital To Analog Converters Overview

The MAX518BCPA is an 8-bit dual-channel voltage-output digital-to-analog converter (DAC) featuring a simple 2-wire serial interface. It operates from a single +5V supply, utilizing the supply voltage as the internal reference for both DAC channels. The device includes precision output buffer amplifiers that allow rail-to-rail output swing. Key electrical parameters include a resolution of 8 bits, a maximum serial clock frequency of 400kHz, and a typical output settling time of 6µs. Supply current is 2.5mA to 6mA in normal mode, reducing to 4µA in shutdown.

Digital To Analog Converters Feature Summary

• Dual 8-bit DAC channels with integrated precision output buffers
• Simple 2-wire serial interface compatible with I2C systems
• Internal reference derived from the single +5V supply voltage
• Power-on reset ensures outputs initialize to 0V

Digital To Analog Converters Applications

• Digital offset and gain adjustment circuits
• Industrial process control systems
• Automatic test equipment (ATE)
• Programmable attenuators
• Minimum component analog systems

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'BCPA' corresponds to the 8-pin Plastic DIP package and the commercial temperature range of 0°C to +70°C. Confirm RoHS compliance status as historical Maxim Integrated documentation may vary regarding lead-free specifications for older manufacturing runs. Ensure the source document explicitly lists this part number variant rather than assuming generic family availability.

Digital To Analog Converters Selection Notes

Select the MAX518BCPA when a dual-channel DAC is required with a single-supply operation. This model is suitable for applications where the supply voltage serves as the reference, eliminating the need for external reference components. Choose this over the MAX517 if two independent outputs are needed, or over the MAX519 if external reference inputs are not required for each channel.

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. While the MAX517 offers a single channel with an external reference input, the MAX518 provides two channels sharing the supply voltage as the reference. The MAX519 expands this to two channels with individual external reference inputs. All variants share the same serial communication protocol.

Digital To Analog Converters Replacement Considerations

Publicly confirmed substitutes within the same datasheet include the MAX517BCPA for single-channel applications and the MAX519BESE+ for dual-channel requirements with external references. Verify pin compatibility and package dimensions before substitution, as the MAX519 utilizes a 16-pin package compared to the 8-pin configuration of the MAX518.
