10-Bit Rail-to-Rail
Micropower DAC with I
2
C Interface
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
voltage range to 2.5V. Selecting the supply as the refer-
ence sets the output voltage range to the supply voltage.
The part features a simple 2-wire serial interface compat-
ible with I
2
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.
