LM612 Dual-Channel parator and Reference February 1995 LM612 Dual-Channel parator and Reference General Description The dual-channel parator consists of two individual parators having an input voltage range that extends down to the negative supply voltage V b The mon open-collector output can be driven low by either half of the LM612 This configuration makes the LM612 ideal for use as a window parator The input stages of the parator have lateral PNP input transistors which maintain low input currents for large differential input voltages and swings above V a The 1 2V voltage reference referred to the Vb terminal is a two-terminal shunt-type band-gap similar to the...
