Description

The HI5810 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 HI5810 features a built-in track and hold.

The conversion time is as low as 10

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.
