DESCRIPTION
Single 12-/10-/8-Bit Rail-to-
Rail DACs with Integrated
Reference in SC70
The LTC2630 is a family of 12-, 10-, and 8-bit voltage-
output DACs with an integrated, high-accuracy, low-drift
reference in a 6-lead SC70 package. It has a rail-to-rail
output buffer and is guaranteed monotonic.
The LTC2630-L has a full-scale output of 2.5V, and
operates from a single 2.7V to 5.5V supply. The
LTC2630-H has a full-scale output of 4.096V, and operates
from a 4.5V to 5.5V supply. Each DAC can also operate in
supply as reference mode, which sets the full-scale output
to the supply voltage.
The parts use a simple SPI/MICROWIRE compatible
3-wire serial interface which operates at clock rates up
to 50MHz.
The LTC2630 incorporates a power-on reset circuit. Op-
tions are available for reset to zero or reset to midscale
after power-up.
