Power-Up and Shutdown Mode
The MAX4122–MAX4129 amplifiers typically settle with-
in 1s after power-up. Using the test circuit of Figure
10, Figures 11 and 12 show the output voltage and
supply current on power-up.
The MAX4123, MAX4125, and MAX4127 have a shut-
down option. When the shutdown pin (SHDN) is pulled
low, the supply current drops below 25A per amplifier
and the amplifiers are disabled with the outputs in a
high-impedance state. Pulling SHDN high or leaving it
floating enables the amplifier. In the dual-amplifier
MAX4129, the shutdown functions operate indepen-
dently. Figures 13 and 14 show the output voltage and
supply current responses of the MAX4123 to a shut-
down pulse.
Power Supplies and Layout
The MAX4122–MAX4129 operate from a single +2.7V
to +6.5V power supply, or from dual supplies of ±1.35V
to ±3.25V. For single-supply operation, bypass the
power supply with a 0.1F ceramic capacitor in parallel
with at least 1F. For dual supplies, bypass each sup-
ply to ground.
Good layout improves performance by decreasing the
amount of stray capacitance at the op amp’s inputs
and outputs. To decrease stray capacitance, minimize
trace lengths and resistor leads by placing external
components close to the op amp’s pins.
