MAX518BCPA+

Digital To Analog Converters Overview

The MAX518BCPA+ is an 8-bit, dual-channel voltage-output digital-to-analog converter (DAC) from the MAX517/MAX518/MAX519 family. It operates on a single +5V supply and utilizes a simple 2-wire serial interface compatible with I2C protocols. The device features internal precision buffer amplifiers that allow rail-to-rail output swing. Total Unadjusted Error (TUE) is specified at ±1.5 LSB for the 'B' grade. Supply current in normal mode is typically 3mA, reducing to 4µA in shutdown.

Digital To Analog Converters Feature Summary

• Dual 8-bit DACs with rail-to-rail buffered outputs
• I2C-compatible 2-wire serial interface
• Internal power-on reset ensures zero-scale startup
• Low-power shutdown mode reduces current consumption

Digital To Analog Converters Applications

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

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CPA+' indicates an 8-pin Plastic DIP package with leaded terminations compliant with RoHS directives. Confirm the 'B' grade designation corresponds to the ±1.5 LSB TUE specification rather than the standard ±1 LSB grade. Ensure the operating temperature range matches the 0°C to +70°C requirement for your application environment.

Digital To Analog Converters Selection Notes

Select this component when a dual-channel DAC with a simple serial interface is required. The MAX518 uses the supply voltage as the reference, unlike the MAX517 or MAX519 which have dedicated reference inputs. Choose this part over the MAX517 if two independent channels are needed, or over the MAX519 if fewer address pins are desired for bus configuration.

Digital To Analog Converters Part Context

The MAX518BCPA+ belongs to the Maxim Integrated MAX51x series of 8-bit DACs. This family provides space-saving solutions in 8-pin DIP and SO packages. The MAX518 specifically offers dual channels sharing a common supply-based reference, distinguishing it from the single-channel MAX517 and the dual-channel MAX519 with individual reference inputs.

Digital To Analog Converters Replacement Considerations

The MAX518ACPA+ serves as a direct functional substitute with tighter accuracy specifications (±1 LSB TUE). Both parts share identical pinouts, interfaces, and electrical characteristics except for the error bounds. Verify that the higher precision grade meets cost constraints before substitution.
