HI3338
8-Bit, CMOS R2R D/A Converter
August 1997
Features
Description
• CMOS Low Power (Typ). . . . . . . . . . . . . . . . . . . .100mW 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.
• R2R Output, Segmented for Low “Glitch”
• CMOS/TTL Compatible Inputs
1
• Fast Settling (Typ) . . . . . . . . . . . . . . . . .20ns to / LSB
2
• Feedthrough Latch for Clocked or Unclocked Use
• Accuracy (Typ) . . . . . . . . . . . . . . . . . . . . . . . . . ±0.5 LSB
• Data Complement Control
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-
• High Update Rate (Typ) . . . . . . . . . . . . . . . . . . . . 50MHz 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.
• Unipolar or Bipolar Operation
• Linearity (INL):
- HI3338KIP . . . . . . . . . . . . . . . . . . . . . . . . . . ±0.75 LSB
The HI3338 is manufactured to give low dynamic power

dissipation, low output capacitance, and inherent latch-up
resistance.
