Description
The HI-7153 is an 8 channel high speed 10 bit A/D converter
which uses a Two Step Flash algorithm to achieve through-put
rates of 200kHz. The converter features an 8 channel CMOS
analog multiplexer with random channel addressing. A unique
switched capacitor technique allows a new input voltage to be
sampled while a conversion is taking place.
Internal high speed CMOS buffers at both the analog and refer-
ence inputs simplifies interface requirements.
A Track and Hold amplifier is included on the chip, consisting of
two high speed amplifiers and an internal hold capacitor,
reducing external circuitry.
Microprocessor bus interfacing is simplified by the use of stan-
dard Chip Select, Read, and Write control signals. The digital
three-state outputs are byte organized for bus interface to 8 or
16 bit systems. An Out-of-Range pin, together with the MSB bit,
can be used to indicate an under or over-range condition.
The HI-7153 operates with ±5V supplies. Only a single +2.5V refer-
ence is required to provide a bipolar input range from -2.5V to
+2.5V.
