DESCRIPTION
The
LTC
®
2635
is a family of quad 12-, 10-, and 8-bit
voltage-output DACs with an integrated, high-accuracy,
low-drift reference in a 16-pin QFN or a 10-lead MSOP
package. It has rail-to-rail output buffers and is guaran-
teed monotonic. The LTC2635-L has a full-scale output
of 2.5V, and operates from a single 2.7V to 5.5V supply.
The LTC2635-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 LTC2635 operates in both the stan-
dard mode (clock rate of 100kHz) and the fast mode (clock
rate of 400kHz). The LTC2635 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.
