The dual-channel comparator LM612AMN consists of two individual comparators, having an input voltage range that extends down to the negative supply voltage Vb. 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 Va.
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 g0.6% 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-BlockTM family, the LM612 is a space-saving monolithic alternative to a multichip solution, offering a high level of integration without sacrificing performance.
