Figure 27. Instrumentation Amplifier
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.
Oscillator frequency is determined by R1, R2, C1, and C2:
fOSC = 1/2ÏRC
where R = R1 = R2 and C = C1 = C2.
Figure 28. Sine-Wave Oscillator
This circuit, as shown, oscillates at 2.0 kHz with a peak-to-peak output swing of 4.5V
