7.3 Power Supply Recommendations

This device is designed to operate from a 0.7V to 2.2V input supply voltage range and a 2.2V to 5.5V bias supply voltage range. Verify the input and bias supplies are well regulated and free of spurious noise. To confirm the output voltage is well regulated and dynamic performance is optimum, verify the input and bias supplies satisfy the following equations:

Equation 10. VOUT(nom) + VDO and VBIAS = VOUT(nom) + VDO(BIAS)
