LM12L458 Datasheet (National Semiconductor) - 12-Bit Sign Data Acquisition System with Self-Calibration

LM12L458, 12-Bit Sign Data Acquisition System with Self-Calibration

The LM12L458 is a highly integrated 3.3V Data Acquisition System.

It combines 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.
