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 oper-
ates 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.
