LM12H458 Description
The LM12458, and LM12H458 are highly integrated Data Acquisition Systems. Operating on just 5V, they bine a fully-differential self-calibrating (correcting linearity and zero errors) 13-bit (12-bit + sign) analogto-digital converter (ADC) and sample-and-hold (S/H) with extensive analog functions and digital functionality. Up to 32 consecutive conversions, using two's plement format, can be stored in an internal...
