Quad/Octal, 2-Wire Serial 8-Bit DACs with Rail-to-Rail Outputs
_______________General Description
The MAX520/MAX521 are quad/octal, 8-bit
voltage-output digital-to-analog converters (DACs) with simple 2-wire serial interfaces that allow communication between multiple devices.
They operate from a single +5V supply and their reference input range includes both supply rails.
The MAX521 includes rail-to-rail output buffer
amplifiers for reduced system size and component count when driving loads.
The MAX520’s unbuffered
voltage outputs reduce the device’s total supply current to 4µA and provide increased accuracy at low output currents.
The MAX520/MAX521 feature a serial int...
