General Description
systems. With a high unity gain frequency and a guaranteed
0.4V/µs slew rate, the quiescent current is only
430µA/amplifier (5V). The input common mode range in-
cludes ground and therefore the device is able to operate in
single supply applications as well as in dual supply applica-
tions. It is also capable of comfortably driving large capaci-
tive loads.
