Dual unbuffered inverter

12. Application information

Some applications are:

• Linear amplifier (see Fig. 11)

• In crystal oscillator design (see Fig. 12)

Remark: All values given are typical unless otherwise specified.

1 µF

Vo(p-p) = VCC - 1.5 V centered at 0.5VCC.

GOL = open loop gain.

Au = voltage amplification.

R1 ≥ 3 kΩ, R2 ≤ 1 MΩ.

ZL > 10 kΩ; GOL = 20 (typical).

Typical unity gain bandwidth product is 5 MHz.

C1

C2

C1 = 47 pF (typical).

C2 = 22 pF (typical).

R1 = 1 MΩ to 10 MΩ (typical).

R2 optimum value depends on the frequency

and required stability against changes in VCC

or average minimum ICC (ICC is typically 2 mA

when VCC = 3.3 V and f = 10 MHz).
