Figure 56 illustrates typical circuit connection.

NOTE: C1– C4: 0.1-µF ceramic and 10-µF electrolytic capacitors typical, depending on power supply quality and pattern

layout.

C5– C8: 0.1-µF ceramic and 10-µF electrolytic capacitors are recommended.

C9, C10: 1-µF non-polar electrolytic capacitors are recommended, which give 27-Hz cutoff frequency.

C11, C12: 0.22-µF electrolytic capacitors are recommended, which give 5-Hz cutoff frequency at PGA gain = 0 dB.

C13, C14: 2.2-µF electrolytic capacitors are typical.

C15: 10-µF electrolytic capacitor is recommended.

R1, R2: 1-kΩ typical is recommended.
