Supply Voltage
1x1
VCC: 3.3 V, ±50 mV ripple
VPA: 3.3 V, ±50 mV ripple

VCC: 3.3 – 5.5 V, ±50 mV ripple
VPA: 3.3 – 5.5 V, ±50 mV ripple
1000*
VCC: 3.3 – 5.5 V ±50 mV ripple
VPA: 3.3 ±3%, ±100 mV ripple
* VCC & VPA may be tied together, provided the supply voltage never falls below
3.3 V and is capable of supplying 1.5 A of current. VCC & VPA are internally
connected on the AC4490-200 only.
