MAX520 - Quad/Octal / 2-Wire Serial 8-Bit DACs

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.

19-0378; Rev 3; 9/96 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 interface and internal software protocol, allowing communication at data rates up to 400kbps.
