MAX4165–MAX4169
High-Output-Drive, Precision, Low-Power, Single-
Supply, Rail-to-Rail I/O Op Amps with Shutdown
12
______________________________________________________________________________________
Power-Up and Shutdown Modes
The MAX4166/MAX4168 have a shutdown option.
When the shutdown pin (SHDN) is pulled low, supply
current drops to 58A per amplifier (VCC = +5V), the
amplifiers are disabled, and their outputs are placed in
a high-impedance state. Pulling SHDN high or leaving it
floating enables the amplifier. In the dual MAX4168, the
two amplifiers shut down independently. Figures 12
and 13 show the MAX4166’s output voltage and sup-
ply-current responses to a shutdown pulse. The
MAX4166–MAX4169 typically settle within 5s after
power-up (Figure 14).
Power Supplies and Layout
The MAX4165–MAX4169 can operate from a single
+2.7V to +6.5V supply, or from dual ±1.35V to
±3.25V supplies. For single-supply operation, bypass
the power supply with a 0.1F ceramic capacitor in
parallel with at least 1F. For dual-supply operation,
bypass each supply to ground. Good layout improves
performance by decreasing the amount of stray capac-
itance at the op amps’ inputs and outputs. Decrease
stray capacitance by placing external components
close to the op amps’ pins, minimizing trace and lead
lengths.
