C6, C7, C4, and C5 are the supply decoupling capacitors for the device. C9 and C12 are prepopulated with 0.1 µF capacitors that usually provide adequate power-supply bypassing for U1. Refer to the instrumentation amplifier data sheet for further information (Table 1-1). Similarly, C8, C10, C11, and C14 can be populated to provide supply bypassing for U2. Additionally, for power-supply bypassing near the device, populate C15 and C20. Refer to the buffer amplifier data sheet for further information on recommended decoupling capacitor values.
