LM12434 12-Bit + Sign Data Acquisition System

The LM12434 and LM12 L 438 are highly integrated Data Acquisition Systems Operating on 3V to 5V they combine a fully-differential self-calibrating (correcting linearity and zero errors) 13-bit (12-bit a sign) analog-to-digital converter (ADC) and sample-and-hold (S H) with extensive analog and digit.
