Intersil HI-7159A
HI-7159A is a monolithic A/D converter that uses a unique dual slope technique which allows it to resolve input changes as small as 1 part in 200,000 (10µV) without the use of critical external components. Its digital autozeroing feature virtually eliminates zero drift over temperature. The device is fabricated in Intersil’ proprietary low noise BiMOS process, resulting in exceptional linearity and noise performance.| Part No. | HI-7159A |
