REI Datasheet
LM615
Quad Comparator and Adjustable Reference
The comparators 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 V+.
The voltage reference is a three-terminal shunt-type band-gap, and is referred to the V- terminal. Two
resistors program the reference from 1.24V to 6.3V, with accuracy of ±0.6% available. The reference
features operation over a shunt current range of 17µA to 20 mA, low dynamic impedance, broad
capacitive load range, and cathode terminal voltage ranging from a diode-drop below V- to above V+.
