FEATURES  
DESCRIPTION  
The LTC®1669 is a 10-bit voltage output DAC with true  
buffered rail-to-rail output voltage capability. It operates  
from a single supply with a range of 2.7V to 5.5V. The  
reference for the DAC is selectable between the supply  
voltage or an internal bandgap reference. Selecting the  
internal bandgap reference will set the full-scale output  
voltagerangeto2.5V.Selectingthesupplyasthereference  
sets the output voltage range to the supply voltage.

Power-On Reset  
The part features a simple 2-wire serial interface compat-  
ible with I C that allows communication between many  
devices. The internal data registers are double buffered to  
allow for simultaneous update of several devices at once.  
The DAC can be put in low current power-down mode for  
use in power conscious systems.

Power-on reset ensures the DAC output is at 0V when  
power is initially applied, and all internal registers are  
cleared. The LTC1669 is pin-for-pin compatible with the  
LTC1663.
