Precision Voltage Comparator
Overview
The LA6311M is a voltage comparator that has low
input currents. It is also designed to operate over a
wide range of supply voltages ; from
15 V op amp
supplies down to the single 5 V supply used for IC
logic. Its output is compatible with TTL as well as
MOS circuits. Offset balancing is provided, and
the outputs can be OR wired.
Features
Response time (100 ns typ).
Operating voltage (+6 V to +36 V).
Single supply operation.
Single circuit.
With input offset trim terminal.
Bipolar technology.
Package outline (MFP8).
