Description
The Intersil HI-7152 is a high speed 10-bit A/D converter
which uses a Two-Step, Flash algorithm to achieve
throughput rates of 200kHz. 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
reference inputs simplify external drive requirements.
A Track and Hold amplifier is included on the chip, consisting
of two high speed amplifiers and an internal hold capacitor.
Microprocessor bus interfacing is simplified by the use of
standard Chip Select, Read, and Write control signals. The
digital three-state outputs are byte organized for interfacing
the either 8-bit or 16-bit systems. An out-of-range pin,
together with the MSB, can be used to indicate an under-
range or over-range condition.
The HI-7152 operates with
±
5V supplies. A single +2.5V
reference is required to provide a bipolar input range from
-2.5V to +2.5V.
