PRODUCT DESCRIPTION
The AD822 is a dual precision, low power FET input op
amp that can operate from a single supply of +3.0 V to 36 V,
or dual supplies of ±1.5 V to ±18 V. It has true single supply
capability with an input voltage range extending below the
negative rail, allowing the AD822 to accommodate input signals
below ground in the single supply mode. Output voltage swing
extends to within 10 mV of each rail providing the maximum
output dynamic range.
如果0-5V供电，那么输入可以支持0V，但是输出可能到不了0V？
