Input Voltage Range and Output Swing
The input range for the MAX4014 family extends from
(VEE - 100mV) to (VCC - 2.25V). Input ground sensing
increases the dynamic range for single-supply applica-
tions. The outputs drive a 2k
load 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
the output-drive capability, since the buffers have a
fixed voltage gain of +2 or -1.
For example, a 50
load can typically be driven from
40mV above VEE to 1.6V below VCC, or 40mV to 3.4V
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 exceed
550A per buffer.
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.
