Pin Description
Detailed Description
The MAX4265–MAX4270 family of operational ampli-
fiers features ultra-low distortion and wide bandwidth.
Their low distortion and low noise make them ideal for
driving high-speed ADCs up to 16 bits in telecommuni-
cations applications and high-performance signal pro-
cessing.
These devices can drive a 100 load and deliver 45mA
while maintaining DC accuracy and AC performance.
The input common-mode voltage ranges from (VEE +
1.6V) to (VCC - 1.6V), while the output typically swings
to within 1.1V of the rails.
Low Distortion
The MAX4265–MAX4270 use proprietary bipolar tech-
nology to achieve minimum distortion in low-voltage
systems. This feature is typically available only in dual-
supply op amps.
Several factors can affect the noise and distortion that a
device contributes to the input signal. The following
guidelines explain how various design choices impact
the total harmonic distortion (THD):
Choose the proper feedback-resistor and gain-resis-
tor values for the application. In general, the smaller
the closed-loop gain, the smaller the THD generated,
especially when driving heavy resistive loads. Large-
value feedback resistors can significantly improve
distortion. The MAX4265–MAX4270’s THD normally
increases at approximately 20dB per decade at fre-
quencies above 1MHz; this is a lower rate than that of
comparable dual-supply op amps.
Operating the device near or above the full-power
bandwidth significantly degrades distortion (see the
Total Harmonic Distortion vs. Frequency graph in the
Typical Operating Characteristics).
The decompensated devices (MAX4266/MAX4267/
MAX4269/MAX4270) deliver the best distortion per-
formance since they have a slightly higher slew rate
and provide a higher amount of loop gain for a given
closed-loop gain setting.
