The AD5305 is a quad 8-bit buffered voltage output DAC in a 10-lead MSOP. The DAC operates from a single 2,5 to 5,5 V supply, consuming only 500 μA at 3 V.
The on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0,7 V/µs. The DAC has a 2-wire serial interface that operates at clock rates up to 400 kHz, and this interface is SMBus compatible at VDD < 3,6 V. Multiple devices can be placed on the same bus. The outputs of all DACs can be updated simultaneously using the software LDAC function.
The power consumption is 3 mW at 5 V,1,5 mW at 3 V, reducing to 1 μW in power-down mode, and this low power consumption of the DAC in normal operation makes it ideally suited for portable battery-operated equipment.
