Specifications of MAX4447EVKIT

• Operating Supply Voltage: 5 V
• Supply Current: 46 mA
• Maximum Power Dissipation: 1600 mW
• Supply Voltage - Max: 5.5 V
• Supply Voltage - Min: 4.5 V

The MAX4447 provides an enable pin (EN) to enable or
disable the output. Table 1 lists the options available for
the enable/disable control jumper, JU1. EN is a TTL/
CMOS-logic level input.
The MAX4447 EV kit layout has been optimized for
high-speed signals with careful attention given to
grounding, power-supply bypassing, and signal-path
layout. The small, surface-mount, ceramic bypass
capacitors (C2, C4) have been placed as close to the
MAX4447 supply pins as possible. Signal traces have
been kept as short as possible by using 0805-sized ter-
mination and gain-set resistors.

To evaluate the MAX4448 or MAX4449, turn off the
power to the EV kit. Replace the MAX4447 with a
MAX4448ESE or MAX4449ESE, and install a gain-set-
ting resistor R
formula:
Note that the gain must be at least +2V/V for the
MAX4448 and must be at least +5V/V for the MAX4449
for the amplifier to be stable.
