In the AD8009 the given operating range is minimum +5V and maximum +/-6V.
I guess it means the maximum voltage I can use is +6V on +Vs and -6V on -Vs. Am I right ?
Hello Fred T,
You are correct -- the data sheet shows that operation up to +Vs = 6V and -Vs = -6V is within specification. Be careful, however, not to exceed 6V on each supply rail (a total of 12V). The total absolute maximum is 12.6V, where continuous operation is not recommended.
AD8009 can have a supply of +/-6V, +12V & GND, +10V & -2V, or other unbalanced supplies as long as it is within the supply rails which is 12V. The amplifier doesn't know where ground is; it only knows where each pin is in relation to other pins. Also take note of its input voltage range (IVR) and the output swing. From the datasheet, both the IVR and the output voltage must have a +/-1.2V headroom from the supply rails. This means that when you use +12V and GND supplies, the lowest input voltage that you may apply is 1.2V and the highest is 10.8V. Your output will also swing from 1.2V to 10.8V.
Hope this helps!
