Description
• Conversion Time . . . . . . . . . . . . . . . . . . . . . . . . . . . 25µs 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 maxi-
mum of 1.0mA (at 25 C) 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.
• Throughput Rate . . . . . . . . . . . . . . . . . . . . . . . .40 KSPS
o
• Built-In Track and Hold
• Single Supply Voltage . . . . . . . . . . . . . . . . . . . . . . +3.3V
o
• Maximum Power Consumption at 25 C. . . . . . . . 3.3mW
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.
