MAX521ACPP+

The MAX521ACPP+ is an 8-bit, quad voltage-output digital-to-analog converter (DAC) manufactured by Maxim Integrated. It utilizes a simple 2-wire serial interface, compatible with I2C protocols, allowing for communication between multiple devices.

This DAC operates from a single +5V supply. The MAX521 variant includes rail-to-rail output buffer amplifiers, which help reduce system size and component count when driving loads. The device features ultra-low supply current consumption of 4µA and can enter a low-power shutdown mode, also consuming 4µA.

Key features include individual DACs with separate reference inputs and a power-on reset function that ensures DAC outputs are at 0V upon initial power application. The serial interface supports data rates up to 400kbps and allows for individual or simultaneous updates of DAC registers due to its double-buffered input configuration.

Applications for this DAC include minimum component analog systems, digital offset/gain adjustment, industrial process control, automatic test equipment, and programmable attenuators. The MAX521ACPP+ is available in a 20-pin SSOP package, designed for space-saving integration.
