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 A at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/s. 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. The references for the four DACs are derived from one reference pin. The outputs of all DACs may be updated simultaneously using the software LDAC function. The parts incorporate a power-on-reset circuit that ensures that the DAC outputs power up to zero volts and remain there until a valid write takes place to the device. There is also a software clear function which resets all input and DAC registers to 0 V. The parts contain a powerdown feature that reduces the current consumption of the devices to 200 nA @ 5 V (80 nA @ 3 V). The low power consumption of these parts in normal operation makes them ideally suited to portable battery-operated equipment. The power consumption is 3 mW at 5 V, 1.5 mW at 3 V, reducing to 1 W in power-down mode.
