MAX518BEPA+

The MAX518BEPA+ is an 8-bit digital-to-analog converter (DAC) from Analog Devices / Maxim Integrated, designed for applications requiring precise analog output control. This dual-channel DAC operates from a single +5V supply and utilizes a simple 2-wire serial interface compatible with I2C communication protocols, allowing for data rates up to 400kbps.

Key features include rail-to-rail output buffer amplifiers, ensuring the output voltage swings across the entire supply range. The MAX518BEPA+ uses the supply voltage as the reference for both DACs. It offers a settling time of 6µs (typical) and an integral non-linearity (INL) of ±1.5 (Max), ±1 (Max). The device operates within a temperature range of -40°C to 85°C.

Packaged in an 8-pin PDIP, the MAX518BEPA+ is suitable for through-hole mounting. Its architecture is R-2R, and it provides a buffered voltage output. The device also includes a power-on reset function that ensures DAC outputs are at 0V upon initial power-up and supports a low-power shutdown mode.

Applications for the MAX518BEPA+ include minimum component analog systems, digital offset/gain adjustment, industrial process control, automatic test equipment, and programmable attenuators.
