2.5 V to 5.5 V, 500 A, 2-Wire Interface Quad Voltage Output 10-Bit DAC

The AD5305 / AD5315 / AD5325 are quad 8-, 10- and 12-bit buffered voltage output DACs in a 10-lead microSOIC package that operate from a single 2.5 V to 5.5 V supply consuming 500 µA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/µs. A 2-wire serial interface is used which operates at clock rates up to 400 kHz. This interface is SMBus-compatible at VDD < 3.6 V. Multiple devices can be placed on the same bus.
