Description
The LTC
®
2633 is a family of dual 12-, 10-, and 8-bit
voltage-output DACs with an integrated, high accuracy,
low drift reference in an 8-lead TSOT-23 package. It has
rail-to-rail output buffers and is guaranteed monotonic.
The LTC2633-L has a full-scale output of 2.5V, and operates
from a single 2.7V to 5.5V supply. The LTC2633-H has a
full-scale output of 4.096V, and operates from a 4.5V to
5.5V supply. Each DAC can also operate with an external
reference, which sets the full-scale output to the external
reference voltage.
These DACs communicate via a 2-wire I
2
C-compatible
serial interface. The LTC2633 operates in both the standard
mode (clock rate of 100kHz) and the fast mode (clock rate
of 400kHz). The LTC2633 incorporates a power-on reset
circuit. Options are available for reset to zero-scale, reset
to mid-scale in internal reference mode, reset to mid-scale
in external reference mode, or reset with all DAC outputs
in a high impedance state after power-up.
