8-Bit, CMOS R2R D/A Converter
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
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 HI3338 is manufactured to give low dynamic power
dissipation, low output capacitance, and inherent latch-up
resistance.

NOTE: 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.
