GENERAL DESCRIPTION
The AD670 is a plete 8-bit signal conditioning analogto-digital converter. It consists of an instrumentation amplifier front end along with a DAC, parator, successive approximation register (SAR), precision voltage reference, and a threestate output buffer on a single monolithic chip. No external ponents or user trims are required to interface, with full accuracy, an analog system to an 8-bit data bus. The AD670 will...
