HI5812
CMOS 20 Microsecond, 12-Bit, Sampling A/D Converter with Internal Track and Hold
Description
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 15µs with a 5V supply.
The twelve data outputs feature full high speed
CMOS threestate bus driver capability, and are latched and held through a full conversion cycle.
The output is user selectable: (i.
e.
) 12bit, 8-bit (MSBs), and/or 4-bit (LSBs).
A data ready flag, and conversion-start inputs complete the digit...
