CA3338, CA3338A
August 1997
CMOS Video Speed, 8-Bit,
50 MSPS, R2R D/A Converters
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
鈥渞ail-to-rail鈥?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, 鈥済litch鈥?/div>
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.
