CMOS 3.3V, 30 Microsecond, 12-Bit,
Sampling A/D Converter with Internal
Track and Hold
The HI5813 is a 3.3V, very low power, 12-bit, successive
approximation analog-to-digital converter. It can operate
from a single 3V to 6V supply and typically draws a
maximum of 1.0mA (at 25^oC) when operating at 3.3V. The
HI5813 features a built-in track and hold. The conversion
time is as low as 25µs with a 3.3V supply.
The twelve data outputs feature full high speed CMOS
three-state bus driver capability, and are latched and held
through a full conversion cycle. The output is user
selectable, i.e., 12-bit, 8-bit (MSBs), and/or 4-bit (LSBs). A
data ready flag and conversion start input complete the
digital interface.
