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 overload 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-low disable
mode that can be used to save power and place the
outputs in a high-impedance state. Drive DISABLE_ with
logic levels, or connect DISABLE_ to VCC for normal
operation. In the dual versions (MAX4268/ MAX4269/
MAX4270), each individual op amp is disabled sepa-
rately, allowing the devices to be used in a multiplex
configuration. The supply current in low-power mode is
reduced to 1.6mA per amplifier. Enable time is typically
100ns, and disable time is typically 750s.
