Typical Single-Supply Applications (V+ = 5.0 VDC)

Additional single-supply applications ideas can be found in

the LM324 datasheet. The LMC660 is pin-for-pin compatible

with the LM324 and offers greater bandwidth and input resis-

tance over the LM324. These features will improve the per-

formance of many existing single-supply applications. Note,

however, that the supply voltage range of the LMC660 is

smaller than that of the LM324.

If R1 = R5, R3 = R6, and R4 = R7; then

∴ A

V ≈100 for circuit shown.

For good CMRR over temperature, low drift resistors should

be used. Matching of R3 to R6 and R4 to R7 affect CMRR.

Gain may be adjusted through R2. CMRR may be adjusted

through R7.

Oscillator frequency is determined by R1, R2, C1, and C2:

fosc = 1/2

πRC, 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.
