The MAX4130–MAX4134 amplifiers typically settle with-
in 1µs after power-up. Figures 9 and 10 show the out-
put voltage and supply current on power-up, using the
test circuit of Figure 8.
The MAX4131 and MAX4133 have a shutdown option.
When the shutdown pin (SHDN) is pulled low, the sup-
ply current drops below 25µA per amplifier and the

amplifiers are disabled with the outputs in a high-
impedance state. Pulling SHDN high or leaving it float-
ing enables the amplifier. In the dual-amplifier
MAX4133, the shutdown functions operate indepen-
dently. Figures 11 and 12 show the output voltage and
supply current responses of the MAX4131 to a shut-
down pulse, using the test circuit of Figure 8.
