Features
• CMOS/SOS Low Power
• R2R Output, Segmented for Low “Glitch”
The CA3338 family are CMOS/SOS high speed R2R voltage
output digital-to-analog converters. They can operate from a
single +5V supply, at video speeds, and can produce
“rail-to-rail” output swings. Internal level shifters and a pin for
an optional second supply provide for an output range below
digital ground. The data complement control allows the
inversion of input data while the latch enable control provides
either feedthrough or latched operation. Both ends of the
R2R ladder network are available externally and may be
modulated for gain or offset adjustments. In addition, “glitch”
energy has been kept very low by segmenting and

thermometer encoding of the upper 3 bits.
• Pb-free Available
The CA3338 is manufactured on a sapphire substrate to give
low dynamic power dissipation, low output capacitance, and
inherent latch-up resistance.

(Pb-free)
Intersil Pb-free products employ special Pb-free material sets;
molding compounds/die attach materials and 100% matte tin plate
termination finish, which is compatible with both SnPb and Pb-free
soldering operations. Intersil Pb-free products are MSL classified at
Pb-free peak reflow temperatures that meet or exceed the Pb-free
requirements of IPC/JEDEC J Std-020B.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
