DESCRIPTION
The LTC
®
2632 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 LTC2632-L has a full-scale output of 2.5V, and operates
from a single 2.7V to 5.5V supply. The LTC2632-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 simple SPI/MICROWIRE
compatible 3-wire serial interface which operates at clock
rates up to 50MHz. The LTC2632 incorporates a power-on
reset circuit. Options are available for reset to zero-scale
or reset to mid-scale in internal reference mode, or reset
to mid-scale in external reference mode after power-up.
