HI5812: CMOS 20µs, 12-Bit, Sampling A/D Converter with Internal Track and Hold

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 20µs 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.
