T he AD5304/AD5314/AD5324 are quad 8, 10 and 12-bit
buffered voltage output DACs in a 10-lead
μ
SOIC pack-
age which operate from a single +2.5V to +5.5V supply
consuming 500
μ
A at 3V. T heir on-chip output amplifiers
allow rail-to-rail output swing to be achieved with a slew
rate of 0.7V/
μ
s. A 3-wire serial interface is used which op-
erates at clock rates up to 30MHz and is compatible with
terface standards.
T he references for the four DACs are derived from one
reference pin. T he outputs of all DACs may be updated
simultaneously using the software
LDAC
function. T he
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. T he parts con-
tains a power-down feature which reduces the current con-
sumption of the device to 200nA @5V (50nA @3V).
T he low power consumption of these parts in normal op-
ated equipment. T he power consumption is 3mW at 5V
reducing to 1μW in power-down mode.
