The AD5337/AD5338/AD5339 are dual 8-, 10-, and 12-bit buffered voltage output DACs, respectively. Each part is housed in an 8-lead MSOP package and operates from a single 2.5 V to 5.5 V supply, consuming 250 μA at 3 V. On-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface 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 two DACs are derived from one reference pin. The outputs of all DACs can be updated simultaneously using the software LDAC function. The parts incorporate a power-on reset circuit to ensure that the DAC outputs power up to 0 V and remain there until a valid write to the device takes place. A software clear function resets all input and DAC registers to 0 V. A power-down feature 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 typically 1.5 mW at 5 V and 0.75 mW at 3 V, reducing to 1 μW in power-down mode.
