Description
The dual-channel comparator consists of two individual comparators having an input voltage range that extends down to the negative supply voltage V b The common open-collector output can be driven low by either half of the LM612 This configuration makes the LM612 ideal for use as a window comparator The input stages of the comparator 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 LM185-1 2 series with voltage accuracy of g 0 6% available The reference features operation over a shunt current range of 17 mA to 20 mA low dynamic impedance and broad capacitive load range As a member of National’s Super-Block TM family the LM612 is a space-saving monolithic alternative to a multichip solution offering a high level of integration without sacrificing performance.
