Description

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 inver-

sion 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 thermom-

eter 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.
