Detailed Description
The MAX4178/MAX4278 are ±5V, wide-bandwidth,
fast-settling, closed-loop buffers featuring high slew
rate, high precision, high output current, low noise, and
low differential gain and phase errors. The MAX4178,
with a -3dB bandwidth of 330MHz, is preset for unity volt-
age gain (0dB). The MAX4278 is preset for a voltage gain
of +2 (6dB) and has a 310MHz -3dB bandwidth.
These devices have a unique input stage that com-
bines the benefits of a current-mode-feedback topolo-
gy (high slew rate and low power) with those of a
traditional voltage-feedback topology. This combination
of architectures results in low input offset voltage and
bias current, and high gain precision and power-supply
rejection.
Under short-circuit conditions, the output current is typ-
ically limited to 150mA. This is low enough that a short
to ground of any duration will not cause permanent
damage to the chip. However, a short to either supply
will create double the allowable power dissipation and
may cause permanent damage if allowed to exist for
longer than approximately 10 seconds. The high out-
put-current capability is an advantage in systems that
transmit a signal to several loads. See the High-
Performance Video Distribution Amplifier section.
