_______________Detailed Desc ription
The MAX4212/MAX4213/MAX4216/MAX4218/MAX4220
are single-supply, rail-to-rail, voltage-feedback ampli-
fiers that employ current-feedback techniques to
achieve 600V/μs slew rates and 300MHz bandwidths.
Excellent harmonic distortion and differential gain/
phase performance make these amplifiers an ideal
choice for a wide variety of video and RF signal-
processing applications.
The output voltage swing comes to within 50mV of each
supply rail. Local feedback around the output stage
assures low open-loop output impedance to reduce
gain sensitivity to load variations. This feedback also
produces demand-driven current bias to the output
transistors for ±100mA drive capability, while constrain-
ing total supply current to less than 7mA. The input
stage permits common-mode voltages beyond the nega-
tive supply and to within 2.25V of the positive supply rail.

Choosing Resistor V alues
Unity-Gain Configuration
The MAX4212/MAX4213/MAX4216/MAX4218/MAX4220
are internally compensated for unity gain. When config-
ured for unity gain, the devices require a 24
resistor
(R
F
) in series with the feedback path. This resistor
improves AC response by reducing the Q of the parallel
LC circuit formed by the parasitic feedback capaci-
tance and inductance.
Inverting and Noninverting Configurations
Select the gain-setting feedback (R
F
) and input (R
G
)
resistor values to fit your application. Large resistor val-
ues increase voltage noise and interact with the amplifi-
er’s input and PC board capacitance. This can
generate undesirable poles and zeros and decrease
bandwidth or cause oscillations. For example, a nonin-
verting gain-of-two configuration (R
F
= R
G
) using 1k
resistors, combined with 1pF of amplifier input capaci-
tance and 1pF of PC board capacitance, causes a pole
at 159MHz. Since this pole is within the amplifier band-
width, it jeopardizes stability. Reducing the 1k
resis-
tors to 100
extends the pole frequency to 1.59GHz,
but could limit output swing by adding 200
in parallel
with the amplifier’s load resistor. Table 1 shows sug-
gested feedback, gain resistors, and bandwidth for
several gain values in the configurations shown in
Figures 1a and 1b.
Layout and Power-S upply Bypassing
These amplifiers operate from a single +3.3V to +11V
power supply or from dual supplies to ±5.5V. For single-
supply operation, bypass V
CC
to ground with a 0.1μF
capacitor as close to the pin as possible. If operating with
dual supplies, bypass each supply with a 0.1μF capacitor.
