Typical Single-Supply Applications

Additional single-supply applications ideas are found in the LM358 data sheet. The LMC603x is pin-for-pin compatible with the LM358 and offers greater bandwidth and input resistance over the LM358. These features can improve the performance of many existing single-supply applications. Be aware, however, the supply voltage range of the LMC603x is smaller than that of the LM358.

If R1 = R5, R3 = R6, and R4 = R7, then AV = 100 for circuit shown.

Use low-drift resistors for good CMRR performance over temperature. Matching of R3 to R6 and R4 to R7 affects CMRR. Gain is adjusted through R2. CMRR is adjusted through R7. An improved circuit can be designed using the RES11A-Q1, low-drift, precision, matched resistor pairs. Figure 6-7 shows how a precise gain of 99 is easily implemented. The capacitors are optional and are be used to improve noise performance, if needed.

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

fOSC = 1/2Ï€RC

where R = R1 = R2 and C = C1 = C2.

This circuit, as shown, oscillates at 2.0kHz with a peak-to-peak output swing of 4.0V.
