HI5812
CMOS 20 Microsecond, 12-Bit, Sampling
A/D Converter with Internal Track and
Hold
The HI5812 is a fast, low power, 12-bit, successive
approximation analog-to-digital converter. It can operate
from a single 3V to 6V supply and typically draws just 1.9mA
when operating at 5V. The HI5812 features a built-in track
and hold. The conversion time is as low as 20
µs with a 5V
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.
An internal clock is provided and is available as an output.
The clock may also be over-driven by an external source.

*Pb-free PDIPs can be used for through hole wave solder
processing only. They are not intended for use in Reflow solder
processing applications.
NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which are RoHS compliant and compatible
with both SnPb and Pb-free soldering operations. Intersil Pb-free
products are MSL classified at Pb-free peak reflow temperatures that
meet or exceed the Pb-free requirements of IPC/JEDEC J STD-020.
