RAIL-TO-RAIL INPUT  
APPLICATIONS INFORMATION  
The input common-mode voltage range of the BUF04701  
extends 100mV beyond the supply rails at room temperature;  
however, due to the fixed gain at G = 1, the output will  
limit the useable input range. This wide swing is achieved  
with a complementary input stage—an N-channel input  
differential pair in parallel with a P-channel differential pair.  
The N-channel pair is active for input voltages close to the  
positive rail, typically (V+) – 2.0V to 100mV above the  
positive supply, while the P-channel pair is on for inputs  
from 100mV below the negative supply to approximately  
(V+) – 1.5V. There is a small transition region, typically  
(V+) – 2.0V to (V+) – 1.5V, in which both pairs are on. This  
500mV transition region can vary ±100mV with process  
variation. Thus, the transition region (both stages on) can  
range from (V+) – 2.1V to (V+) – 1.4V on the low end, up to  
(V+) – 1.9V to (V+) – 1.6V on the high end.  
Figure 1 shows the BUF04701 connected as a buffer. Power  
supplies should be bypassed with capacitors connected  
close to the device pins. Capacitor values as low as 0.1µF  
will assure stable operation in most applications, but high  
output current and fast output slewing can demand large  
current transients from the power supplies.  
Rail-to-rail input and output swing helps maintain dynamic  
range, especially in low supply applications. Figure 2 shows  
the input and output waveforms for the BUF04701. On a ±6V  
supply with a 100kΩ load connected to VS/2, the output is  
tested to swing within 50mV to the rail.  
OPERATING VOLTAGE  
The BUF04701 is fully specified and tested from 3.5V to 12V  
over a temperature range of –40°C to +125°C. Parameters  
that vary significantly with operating voltages or temperature  
are shown in the Typical Characteristic Curves.  
INPUT PROTECTION  
Device inputs are protected by ESD diodes that will conduct  
if the input voltages exceed the power supplies by more than  
approximately 300mV. Momentary voltages greater than  
300mV beyond the power supply can be tolerated if the  
current is limited to 10mA. This is easily accomplished with  
an input resistor, in series with the buffer input shown in  
Figure 3. Many input signals are inherently current-limited to  
less than 10mA; therefore, a limiting resistor is not always  
required. The BUF04701 features no phase inversion when  
the inputs extend beyond supplies if the input current is  
limited, as shown in Figure 4.
