Dual Voltage Output, 8-/10-/12-Bit DACs
GENERAL DESCRIPTION
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 V
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 equip-
ment. 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.
