Description

The comparators LM615 have an input range which extends to the negative supply, and have open-collector outputs. Improved over the LM139 series, the input stages of the comparators have lateral PNP input transistors which enable low input currents for large differential input voltages and swings above Va.

The voltage reference of LM615 is a three-terminal shunt-type bandgap, and is referred to the Vb terminal. Two resistors program the reference from 1.24V to 6.3V, with accuracy of g0.6% available. The reference features operation over a shunt current range of 17 mA to 20 mA, low dynamic impedance,broad capacitive load range, and cathode terminal voltage ranging from a diode-drop below Vb to above Va.

As a member of National's Super-BlockTM family, the LM615 is a space-saving monolithic alternative to a multichip solution, offering a high level of integration without sacrificing performance.
