LM12H458 Datasheet (National Semiconductor) - 12-Bit Sign Data Acquisition System

LM12H458, 12-Bit Sign Data Acquisition System

The LM12454, LM12458, and LM12H458 are highly integrated Data Acquisition Systems.

Operating on just 5V, they combine a fully-differential self-calibrating (correcting linearity and zero errors) 13-bit (12-bit + sign) analog-to-digital converter (ADC) and sample-and-hold (S/H) with extensive analog
