rejection ratio of 95dB (typ) allows the devices to be
powered directly from a battery, simplifying design and
extending battery life.
Power-Up Settling Time
The MAX9910–MAX9913 typically require 5s 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 18s for VDD = 3V (see the Typical Operating
Characteristics for power-up settling time).
Shutdown Mode
The MAX9911/MAX9913 feature active-low shutdown
inputs. The MAX9911/MAX9913 enter shutdown in 2s
(typ) and exit in 30s (typ). The amplifiers’ outputs are
in a high-impedance state in shutdown mode. Drive
SHDN low to enter shutdown. Drive SHDN high to
enable the amplifier. The MAX9913 dual-amplifier fea-
tures separate shutdown inputs. Shut down both ampli-
fiers for the lowest quiescent current.
Power-Supply Bypassing and Layout
To minimize noise, bypass VDD with a 0.1F capacitor
to ground, as close to the pin as possible.
Good layout techniques optimize performance
by decreasing the amount of stray capacitance and
inductance to the op amps’ inputs and outputs.
Minimize stray capacitance and inductance by placing
external components close to the IC.
