With Isolation Resistor
be maintained using an amplifier with very low output
impedance at high frequencies. The combination of
high speed, fast slew rate, low noise, and a low and
stable distortion over load makes the MAX4265–
MAX4270 ideally suited for use as buffer amplifiers in
high-speed ADC applications.
Low-Power Disable Mode
The MAX4265–MAX4270 feature an active-high enable
pin that can be used to save power and place the out-
puts in a high-impedance state. Drive EN_ with logic
levels or connect EN_ to V
CC
for normal operation. In
the dual versions (MAX4268/MAX4269/MAX4270),
each individual op amp is enabled separately, allowing
the devices to be used in a multiplex configuration. The
supply current in low-power mode is reduced to 1.6mA
per device. Enable time is typically 100ns, and disable
time is typically 750μs.
