FEATURES  
GENERAL DESCRIPTION  
AD5305: 4 Buffered 8-Bit DACs in 10-Lead MSOP  
A Version: ؎1 LSB INL, B Version: ؎0.625 LSB INL  
AD5315: 4 Buffered 10-Bit DACs in 10-Lead MSOP  
A Version: ؎4 LSB INL, B Version: ؎2.5 LSB INL  
AD5325: 4 Buffered 12-Bit DACs in 10-Lead MSOP  
A Version: ؎16 LSB INL, B Version: ؎10 LSB INL  
Low Power Operation: 500 A @ 3 V, 600 A @ 5 V  
2-Wire (I2C® Compatible) Serial Interface  
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  
Three Power-Down Modes  
Double-Buffered Input Logic  
Output Range: 0 V to VREF  
The AD5305/AD5315/AD5325 are quad 8-, 10-, and 12-bit  
buffered voltage output DACs in a 10-lead MSOP 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  
with a slew rate of 0.7 V/µs. A 2-wire serial interface, which  
operates at clock rates up to 400 kHz, is used. This interface is  
SMBus compatible at VDD < 3.6 V. Multiple devices can be  
placed on the same bus.  
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, which ensures that the DAC outputs power  
up to 0 V and remain there until a valid write takes place to the  
device. There is also a software clear function that resets all input  
and DAC registers to 0 V. The parts contain a power-down  
feature that reduces the current consumption of the devices to  
200 nA @ 5 V (80 nA @ 3 V).  
Power-On Reset to 0 V  
Simultaneous Update of Outputs (LDAC Function)  
Software Clear Facility  
Data Readback Facility  
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.
