HI5813
August 1997
CMOS 3.
3V, 25 Microsecond, 12-Bit, Sampling A/D Converter with Internal Track and Hold
Description
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 25oC) 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 threestate 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).
