Precision, High-Bandwidth Op Amp
MAX9622

Detailed Description
The MAX9622 is a power-efficient, high-speed op amp
ideal for capturing fast edges in a wide variety of signal
processing applications.
It precisely calibrates its VOS on power-up to eliminate
the effects of package stresses, power supplies, and
temperature.
Applications Information
Power-Up Autotrim
The MAX9622 features power-up autotrimming that
allows the devices to achieve less than 100FV of input
offset voltage. The startup sequence takes approxi-
mately 4ms to complete after the supply voltage exceeds
an internal threshold of 1.8V. During this time, the inputs
and outputs are connected to an auxiliary amplifier that
has an input offset of 5mV (typ). As soon as the auto-
trimming is completed, the inputs and outputs switch
from the auxiliary amplifier to the calibrated amplifier.
The calibration settings hold until the supply voltage
drops below an internal threshold of 1.4V. This could be
used to recalibrate the amplifier. The supply current of
the part increases to about 2.5mA during the power-up
autotrim period. Use good supply decoupling with low
ESR capacitors.
Active Filters
The MAX9622 is ideal for a wide variety of active filter
circuits that make use of their wide output voltage swings
and large bandwidth capabilities. The Typical Application
Circuit shows a multiple feedback active filter circuit
example with a 100kHz corner frequency. At low frequen-
cies, the amplifier behaves like a simple low-distortion
inverting amplifier gain = -1, while its high bandwidth
gives excellent stopband attenuation above its corner
frequency. See the Typical Application Circuit.
Input Differential Voltage Protection
During normal op-amp operation, the inverting and non-
inverting inputs of the MAX9622 are at essentially the
same voltage. However, either due to fast input voltage
transients or due to loss of negative feedback, these pins
can be forced to different voltages. Internal back-to-back
diodes and series resistors protect input-stage transis-
tors from large input differential voltages (see Figure 2).
IN+ and IN- can survive any voltage between the power-
supply rails.
This op amp has been designed to exhibit no phase
inversion to overdriven inputs.
