_______________De t a ile d De s c rip t io n  
The MAX4012/MAX4016/MAX4018/MAX4020 are sin-  
gle-supply, rail-to-rail, voltage-feedback amplifiers that

600V/µs slew rates and 200MHz 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 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 ±120mA 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.  
verting gain-of-two configuration (R = R ) using 1kΩ

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 1kΩ resis-  
tors to 100Ω extends the pole frequency to 1.59GHz,  
but could limit output swing by adding 200Ω in parallel  
with the amplifier’s load resistor. Table 1 shows sug -
