Typical Single-Supply Applications (V+ = 5.0 V_DC) (Continued)
Low-Leakage Sample-and-Hold
Sine-Wave Oscillator
DS011227-17
Oscillator frequency is determined by R1, R2, C1, and C2:
f_OSC = 1/2πRC
where R = R1 = R2 and C = C1 = C2.
This circuit, as shown, oscillates at 2.0 kHz with a
peak-to-peak output swing of 4.5V
1 Hz Square-Wave Oscillator
