2.5 V to 5.5 V, 500 A, Quad Voltage Output  
a
8-/10-/12-Bit DACs in 10-Lead microSOIC  
AD5304/AD5314/AD5324*  
GENERAL DESCRIPTION  
FEATURES  
The AD5304/AD5314/AD5324 are quad 8-, 10- and 12-bit  
AD5304  
buffered voltage output DACs in a 10-lead microSOIC package  
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 which operates at clock rates  
up to 30 MHz and is compatible with standard SPI, QSPI,  
MICROWIRE and DSP interface standards.  
Four Buffered 8-Bit DACs in 10-Lead microSOIC  
AD5314  
Four Buffered 10-Bit DACs in 10-Lead microSOIC  
AD5324  
Four Buffered 12-Bit DACs in 10-Lead microSOIC  
Low Power Operation: 500 A @ 3 V, 600 A @ 5 V  
2.5 V to 5.5 V Power Supply  
Guaranteed Monotonic By Design Over All Codes  
Power-Down to 80 nA @ 3 V, 200 nA @ 5 V  
Double-Buffered Input Logic  
Output Range: 0–VREF  
Power-On-Reset to Zero Volts  
Simultaneous Update of Outputs (LDAC Function)  
Low Power, SPI™, QSPI™, MICROWIRE™, and  
DSP-Compatible 3-Wire Serial Interface  
On-Chip Rail-to-Rail Output Buffer Amplifiers  
Temperature Range –40؇C to +105؇C  
The references for the four DACs are derived from one reference  
pin. The outputs of all DACs may be updated simultaneously  
using the software LDAC function. The 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. 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.
