GENERAL DESCRIPTION

The AD5304/AD5314/AD5324

buffered voltage output DACs in 10-lead MSOP and 10-lead

LFCSP packages that operate from a single 2.5 V to 5.5 V supply,

consuming 500 μA at 3 V. Their on-chip output amplifiers allow

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 function. The parts incorporate a power-on

reset circuit, and ensure that the DAC outputs power up to 0 V

and remains there until a valid write takes place to the device.

The parts contain a power-down feature that reduces the current

consumption of the device 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 μW in power-down mode.
