Typical Single-Supply Applications
Additional single-supply applications ideas can be found in
the LM358 datasheet. The LMC662 is pin-for-pin compatible
with the LM358 and offers greater bandwidth and input resis-
tance over the LM358. These features will improve the per-
formance of many existing single-supply applications. Note,
however, that the supply voltage range of the LM662 is
smaller than that of the LM358.

For good CMRR over temperature, low drift resistors should
be used. Matching of R3 to R6 and R4 to R7 affects CMRR.
Gain may be adjusted through R2. CMRR may be adjusted
through R7.
This circuit, as shown, oscillates at 2.0 kHz with a
peak-to-peak output swing of 4.5V
