Description

The HI5810 is a fast, low power, 12-bit, successiveapproximation, 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 of HI5810  is as low as 10µs 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., 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.
