Maximum Vo(p-p) = VCC − 1.5 V centered at

0.5 × VCC.

Gv = –-1----+------RR--------12---G--(--1-o--l-+-----G-----o---l-)-

Gol = open loop gain

Gv = voltage gain

R1 ≥ 3 kΩ, R2 ≤ 1 MΩ

ZL > 10 kΩ; Gol = 20 (typ.)

Typical unity gain bandwidth product is 5 MHz.

C1 = 47 pF (typ.)

C2 = 22 pF (typ.)

R1 = 1 MΩ to 10 MΩ (typ.)

R2 optimum value depends on the frequency and

required stability against changes in VCC or average

minimum ICC (ICC is typically 2 mA at VCC = 3 V and

f = 1 MHz).
