10 Power Supply Recommendations

The LM48560 device is designed be operate with a power supply between 2.7 V and 5.5 V. Proper power supply bypassing is critical for low noise performance and high PSRR. Place the supply bypass capacitors as close to the device as possible. Place a 1-μF ceramic capacitor from VDD to GND. Additional bulk capacitance may be added as required.
