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 resistance over the LM324. These features
will improve the performance of many existing single-supply applications. Note, however, that the supply voltage
range of the LMC660 is smaller than that of the LM324.

≈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.
