from the op amp’s output.
Applications Information
Shutdown Mode
The MAX4401 features a low-power shutdown mode.
When
SHDN
goes low, the supply current drops to
0.1μA (typical). The output enters a high-impedance
state. Pull
SHDN
high to enable the amplifier. Do not
leave
SHDN
floating. Figure 4 shows the shutdown
waveform.
Power-Up
The MAX4400–MAX4403 outputs typically settle within
5μs after power-up. Figure 5 shows the output voltage
on power-up and power-down.
Power Supplies and Layout
The MAX4400–MAX4403 operate from a single +2.5V
to +5.5V power supply. Bypass the power supply with a
0.1μF capacitor to ground.
Good layout techniques optimize performance by
decreasing the amount of stray capacitance at the op
amp’s inputs and outputs. To decrease stray capaci-
tance, minimize trace lengths by placing external com-
ponents close to the op amp’s pins.
