Description
The HI3338 family are CMOS 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 lad-
der 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 encod-
ing of the upper 3 bits.
The HI3338 is manufactured to give low dynamic power
dissipation, low output capacitance, and inherent latch-up
resistance.
