HI3338KIB集成電路（IC）的數(shù)模轉換器（DAC）規(guī)格書PDF中文資料

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 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.
