when operating from a single +5V supply. If the buffer is  
operated in the noninverting, gain of +2 configuration  
with the inverting input grounded, the effective input  
voltage range becomes 20mV to 1.7V, instead of the  
-100mV to 2.75V indicated by the Electrical Character-  
istics. Beyond the effective input range, the buffer out-  
put is a nonlinear function of the input, but it will not  
undergo phase reversal or latchup.

Enable  
The MAX4019 has an enable feature (EN_) that allows  
the buffer to be placed in a low-power state. When the  
buffers are disabled, the supply current will not eꢀceed  
550µA per buffer.

CC  
As the voltage at the EN_ pin approaches the negative  
supply rail, the EN_ input current rises. Figure 2 shows  
a graph of EN_ input current versus EN_ pin voltage.  
Figure 3 shows the addition of an optional resistor in  
series with the EN pin, to limit the magnitude of the cur-  
rent increase. Figure 4 displays the resulting EN pin  
input current to voltage relationship.  
increases the dynamic range for single-supply applica-  
tions. The outputs drive a 2kload to within 60mV of  
the power-suply rails. With heavier loads, the output  
swing is reduced as shown in the Electrical Character-  
istics and the Typical Operating Characteristics. As the  
load increases, the input range is effectively limited by
