Power-Supply Considerations
The MAX9914–MAX9917 are optimized for single 1.8V
to 5.5V supply operation. A high amplifier power-supply
rejection ratio of 85dB (typ) allows the devices to be
powered directly from a battery, simplifying design and
extending battery life.
Power-Up Settling Time
The MAX9914–MAX9917 typically require 2s after
power-up. Supply settling time depends on the supply
voltage, the value of the bypass capacitor, the output
impedance of the incoming supply, and any lead resis-
tance or inductance between components. Op amp
settling time depends primarily on the output voltage
and is slew-rate limited. Figure 3 shows the MAX991_ in
a noninverting voltage follower configuration with the
input held at midsupply. The output settles in approxi-
mately 3.5s for VDD = 3V (see the Typical Operating
Characteristics for the Power-Up Settling Time graph).
Shutdown Mode
The MAX9915 and MAX9917 feature active-low shut-
down inputs. The MAX9915 and MAX9917 enter shut-
down in 2s (typ) and exit shutdown in 10s (typ). The
amplifiers’ outputs are high impedance in shutdown
mode. Drive SHDN low to enter shutdown. Drive SHDN
high to enable the amplifier. The MAX9917 dual amplifi-
er features separate shutdown inputs. Shut down both
amplifiers for lowest quiescent current.
Power-Supply Bypassing and Layout
Bypass VDD with a 0.1F capacitor to ground as close
to the pin as possible to minimize noise.
Good layout techniques optimize performance by
decreasing the amount of stray capacitance and induc-
tance to the op amp’s inputs and outputs. Minimize
stray capacitance and inductance, by placing external
components close to the IC.
