9 Power Supply Recommendations

The THS4567 device is principally intended to operate with a nominal single-supply voltage of 3.3 V to 5.5 V. Split (or bipolar) supplies can be used with the THS4567 device, as long as the total value across the device remains less than 5.5 V. A low power-supply source impedance must be maintained across frequency so use multiple bypass capacitors in parallel. Place the bypass capacitors as close to the supply pins as possible. Place the smallest capacitor (< 10 nF) on the same side of the PCB as the THS4567 device. Larger capacitors (> 1 µF) can be placed further away and shared among different devices in the system.
