MAX4395 Maxim, MAX4395 Datasheet - Page 11

• Manufacturer Part Number: MAX4395
• Description: The MAX4389/MAX4390/MAX4392–MAX4396 family of op amps are unity-gain stable devices that combine high-speed performance, rail-to-rail outputs, and disable mode
• Manufacturer: Maxim

The MAX4389/MAX4390/MAX4392–MAX4396 are dual-
supply, rail-to-rail, voltage-feedback amplifiers that
employ current-feedback techniques to achieve
500V/µs slew rates and 85MHz bandwidths. Excellent
harmonic distortion and differential gain/phase perfor-
mance make these amplifiers an ideal choice for a wide
variety of video and RF signal-processing applications.
The output voltage swings to within 200mV of each
supply rail. Local feedback around the output stage
ensures low open-loop output impedance to reduce

gain sensitivity to load variations. The input stage per-
mits common-mode voltages to the negative supply
and to within 2.25V of the positive supply rail.
The MAX4389/MAX4390/MAX4392–MAX4396 are inter-
nally compensated for unity gain. When configured for
unity gain, a 24Ω resistor (R
back path optimizes AC performance. This resistor
improves AC response by reducing the Q of the paral-
lel LC circuit formed by the parasitic feedback capaci-
tance and inductance.
