__________Applications Information
Power-Up
The MAX4330–MAX4334 outputs typically settle within
5s after power-up. Using the test circuit of Figure 7,
Figures 8 and 9 show the output voltage and supply
current on power-up and power-down.
Shutdown Mode
The MAX4331/MAX4333 feature a low-power shutdown
mode. When the shutdown pin (SHDN) is pulled low, the
supply current drops to 9A per amplifier (typical), the
amplifier is disabled, and the outputs enter a high-
impedance state. Pulling SHDN high or leaving it float-
ing enables the amplifier. Figures 10 and 11 show the
MAX4331/MAX4333’s output voltage and supply-current
responses to a shutdown pulse.
