Gol = open loop gain

Gv = voltage gain

R1  3 k, R2  1 M

ZL > 10 k; Gol = 20 (typical)

VCC = 6.0 V

Typical unity gain bandwidth product is 5 MHz.

R1 = 1 M to 10 M (typical

R2 optimum value depends on the frequency and

required stability against changes in VCC or average

minimum ICC. ICC is typically 5 mA at VCC = 5 V and

fi = 10 MHz.
