Description
The Intersil CA3310 is a fast, low power, 10-bit successive
approximation analog-to-digital converter, with microprocessor-
compatible outputs. It uses only a single 3V to 6V supply and
typically draws just 3mA when operating at 5V. It can accept full
rail-to-rail input signals, and features a built-in track and hold.
The track and hold will follow high bandwidth input signals, as it
has only a 100ns (typical) input time constant.
The ten data outputs feature full high-speed CMOS three-
state bus driver capability, and are latched and held through
a full conversion cycle. Separate 8 MSB and 2 LSB enables,
a data ready flag, and conversion start and ready reset
inputs complete the microprocessor interface.
An internal, adjustable clock is provided and is available as
an output. The clock may also be driven from an external
source.
