CMOS Video Speed, 8-Bit, 50 MSPS, R2R D/A Converters

DATASHEET

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.

The CA3338 is manufactured on a sapphire substrate to

give low dynamic power dissipation, low output capacitance,

and inherent latch-up resistance.

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.
