Извините, но мне кажется, что Вы что-то спутали.
Редко. Но чаще, чем хотелось бы... А тут - нет.
The AD623 is designed to drive loads of 10 kΩ or greater. If
the load is less than this value, the output of the AD623 should
be buffered with a precision single-supply op amp, such as the
OP113. This op amp can swing from 0 V to 4 V on its output
while driving a load as small as 600 Ω. Table 7 summarizes the
performance of some buffer op amps
