AD5305/AD5315/AD5325 is a 2.5V to 5.5V quad voltage output DAC with features such as low power operation, 2-wire interface, and guaranteed monotonicity.
The AD5305/AD5315/AD5325 are quad 8-, 10-, and 12-bit buffered voltage output DACs in a 10-lead MSOP package. They operate from a single 2.5 V to 5.5 V supply and feature on-chip output amplifiers that allow rail-to-rail output swing with a slew rate of 0.7 V/µs. The devices utilize a 2-wire serial interface compatible with SMBus at voltages below 3.6 V, allowing multiple devices to be placed on the same bus.
