HI5812 - Sampling A/D Converter

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.

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 digital interface. An internal clock is provided and is available as an output. The clock may also be over-driven by an external sour.
