Note 1 The offset voltage and inverting input current can be adjusted with an external 10 kX pot between pins 1 and 5 with the
wiper connected to V
CC
(Pin 7) to make the output offset voltage zero
Note 2 A heat sink is required to keep the junction temperature below the absolute maximum when the output is short circuited
