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.
Applications
• Fast, No-Droop, Sample and Hold
An internal, adjustable clock is provided and is available as
an output. The clock may also be driven from an external
source.
• Voice Grade Digital Audio
• DSP Modems
• Remote Low Power Data Acquisition Systems
• µP Controlled Systems
