LM12L458 Description

The LM12L458 is a highly integrated 3.3V Data Acquisition System. It bines 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 functions and digital functionality. Up to 32 consecutive conversions, using two's plement format, can be stored in an internal 32-word (16-bit wide) FIFO data...
