MAX4382 Maxim, MAX4382 Datasheet - Page 10

• Manufacturer Part Number: MAX4382
• Description: The MAX4380–MAX4384 family of op amps are unity-gain-stable devices that combine high-speed performance, rail-to-rail outputs, and high-impedance disable mode
• Manufacturer: Maxim

Ultra-Small, Low-Cost, 210MHz, Single-Supply
Op Amps with Rail-to-Rail Outputs and Disable
The MAX4380–MAX4384 are single-supply, rail-to-rail,
voltage-feedback amplifiers that employ current-feed-
back techniques to achieve 485V/µs slew rates and
210MHz bandwidths. Excellent harmonic distortion and
differential gain/phase performance make these ampli-
fiers an ideal choice for a wide variety of video and RF
signal-processing applications.
The output voltage swings to within 50mV of each sup-
ply 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 beyond the negative sup-
ply and to within 2.25V of the positive supply rail.

AC performance. This resistor improves AC response
by reducing the Q of the parallel LC circuit formed by
the parasitic feedback capacitance and inductance.
The MAX4380–MAX4384 are low-power, voltage-feed-
back amplifiers featuring bandwidths up to 210MHz,
0.1dB gain flatness to 55MHz. They are designed to
minimize differential-gain error and differential-phase
error to 0.02% and 0.08 degrees respectively. They
