Note 1 The offset voltage and inverting input current can be adjusted with an external 10 k
X pot between pins 1 and 5 with the
wiper connected to VCC (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
Note 3 VCM e g10V
Note 4 g45V s VS s g18V
Note 5 Full Power Bandwidth is guaranteed based on Slew Rate measurement FPBW e SR2
