will need to change in order to meet ON Semiconductor’s system requirements. Since the ON Semiconductor
product management systems do not have the ability to manage part nomenclature that utilizes an underscore

General Description
Overdrive Recovery
The FAN4174 amplifier includes single-supply, generalpurpose, voltage-feedback amplifiers, fabricated on a biCMOS process. The family features a rail-to-rail input
and output and is unity gain stable. The typical noninverting circuit schematic is shown in Figure 21.
Overdrive of an amplifier occurs when the output and/or
input ranges are exceeded. The recovery time varies
based on whether the input or output is overdriven and
by how much the range is exceeded. The FAN4174
typically recovers in less than 500 ns from an overdrive
condition. Figure 23 shows the FAN4174 amplifier in an
overdriven condition.
Figure 21. Typical Non-inverting Configuration
Figure 23. Overdrive Recovery
Input Common Mode Voltage
Driving Capacitive Loads
The common mode input range extends to 300 mV
below ground and to 100 mV above VS in single supply
operation. Exceeding these values does not cause
phase reversal; however, if the input voltage exceeds
the rails by more than 0.5 V, the input ESD devices
begin to conduct. The output stays at the rail during this
overdrive condition. If the absolute maximum input VIN
(700 mV beyond either rail) is exceeded, externally limit
the input current to ±5 mA, as shown in Figure 22.
Figure 9 illustrates the response of the FAN4174
amplifier. A small series resistance (RS) at the output of
the amplifier, illustrated in Figure 24, improves stability
and settling performance. RS values in Figure 9 achieve
maximum bandwidth with less than 2 dB of peaking. For
maximum flatness, use a larger RS. Capacitive loads
larger than 500 pF require the use of RS.
Figure 24. Typical Topology for Driving a
Capacitive Load
Figure 22. Circuit for Input Current Protection
Driving a capacitive load introduces phase-lag into the
output signal, which reduces phase margin in the
amplifier. The unity gain follower is the most sensitive
configuration. In a unity gain follower configuration, the
FAN4174 amplifier requires a 300 series resistor to
drive a 100 pF load.
Power Dissipation
The maximum internal power dissipation allowed is
directly related to the maximum junction temperature. If
the maximum junction temperature exceeds 150°C,
performance degradation occurs. If the maximum
junction temperature exceeds 150°C for an extended
time, device failure may occur.

General layout and supply bypassing play major roles in
high-frequency performance. Fairchild evaluation
boards help guide high-frequency layout and aid in
device testing and characterization. Follow the steps
below as a basis for high-frequency layout:
1.
Include 6.8 μF and 0.01 μF ceramic capacitors.
2.
Place the 6.8 μF capacitor within 19.05 mm
(0.75 inches) of the power pin.
3.
Place the 0.01 μF capacitor within 2.54 mm (0.1
inches) of the power pin.
4.
Remove the ground plane under and around the
part, especially near the input and output pins, to
reduce parasitic capacitance.
Minimize all trace lengths to reduce series inductances.
Refer to the evaluation board layouts shown in Figure
27 through Figure 30 for more information.
When evaluating only one channel, complete the
following on the unused channel:
1.
Ground the non-inverting input.
2.
Short the output to the inverting input.
