GENERAL DESCRIPTION  
The AD5308/AD5318/AD5328 are octal 8-, 10-, and 12-bit  
buffered voltage output DACs in a 16-lead TSSOP. They operate  
from a single 2.5 V to 5.5 V supply, consuming 0.7 mA typ at 3 V.  
Their on-chip output amplifiers allow the outputs to swing  
rail-to-rail with a slew rate of 0.7 V/µs. The AD5308/AD5318/  
AD5328 use a versatile 3-wire serial interface that operates at  
clock rates up to 30 MHz and is compatible with standard  
SPI, QSPI, MICROWIRE, and DSP interface standards.  
The references for the eight DACs are derived from two reference  
pins (one per DAC quad). These reference inputs can be  
configured as buffered, unbuffered, or VDD inputs. 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 to  
the device takes place. The outputs of all DACs may be updated  
simultaneously using the asynchronous LDAC input. The parts  
contain a power-down feature that reduces the current consump-  
tion of the devices to 400 nA at 5 V (120 nA at 3 V). The eight  
channels of the DAC may be powered down individually.  
Simultaneous Update of Outputs (LDAC)  
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  
APPLICATIONS  
Portable Battery-Powered Instruments  
Digital Gain and Offset Adjustment  
Programmable Voltage and Current Sources  
Optical Networking  
All three parts are offered in the same pinout, which allows  
users to select the resolution appropriate for their application  
without redesigning their circuit board.
