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

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.
