GENERAL DESCRIPTION
The AD5324-EP
in a 10-lead MSOP package that operates from a single 2.5 V to
5.5 V supply, consuming 500 μA at 3 V. Its on-chip output
amplifiers allows rail-to-rail output swing to be achieved with a
slew rate of 0.7 V/μs. A 3-wire serial interface is used; it operates
at clock rates up to 30 MHz and is compatible with standard SPI,
QSPI™, MICROWIRE™, and DSP interface standards.
The references for the four DACs are derived from one reference
pin. The outputs of all DACs can be updated simultaneously using
the software LDAC
reset circuit, and ensures that the DAC outputs power up to 0 V
and remains there until a valid write takes place to the device.
The part contains a power-down feature that reduces the current
consumption of the device to 200 nA at 5 V (80 nA at 3 V).
The low power consumption of this part in normal operation
makes it ideally suited to portable battery-operated equipment. The
power consumption is 3 mW at 5 V, and 1.5 mW at 3 V, reducing
to 1 μW in power-down mode.
Full details about this enhanced product are available in the
AD5324
