Description
The FAN4113 is a low cost, voltage feedback amplifier that
consumes only 640
µA of supply current. The FAN4113 is
designed to operate from +1.2V to 5.5V (±2.75V) supplies.
The common mode voltage range extends below the negative
rail and the output provides rail-to-rail performance.
The FAN4113 is designed on a complementary bipolar
process and provides 36MHz of bandwidth and 8V/
µs of slew
rate at a low supply voltage of 1.2V. The combination of low
power, rail-to-rail performance, low voltage operation, and
tiny package options make the FAN4113 well suited for use
in personal electronics equipment such as cellular handsets,
pagers, PDAs, and other battery powered applications.

Application Information
General Description
The FAN4113 is single supply, general purpose, voltage-feedback
amplifier. The FAN4113 is fabricated on a complimentary bipolar
process, features a rail-to-rail output, and is unity gain stable.
The typical non-inverting circuit schematic is shown in Figure 1.
Figure 1: Typical Non-inverting Configuration
RR Applications and Beyond
The FAN4113 can be used with input signals that exceed
its common mode input voltage range. Simply attenuate the
input signal and increase the gain of the FAN4113, see
Figure 2. First, select A1 so the FAN4113 common voltage
range is not exceeded. Second, select Rf and Rg to get the
desired overall gain for signal Vin. Finally, pick VDC for the
desired output offset.
Figure 2: RR Applications and Beyond
Power Dissipation
The maximum internal power dissipation allowed is directly
related to the maximum junction temperature. If the maximum
junction temperature exceeds 150°C, some performance
degradation will occur. It the maximum junction temperature
exceeds 175°C for an extended time, device failure may occur.
Overdrive Recovery
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 ranges are exceeded. The FAN4113 will typically recover
in less than 50ns from an overdrive condition. Figure 3
shows the FAN4113 in an overdriven condition.
Figure 3: Overdrive Recovery
Driving Capacitive Loads
The Frequency Response vs. CL plot, illustrates the response
of the FAN4113. A small series resistance (Rs) at the output
of the amplifier, illustrated in Figure 4, will improve stability
and settling performance.

Layout Considerations
General layout and supply bypassing play major roles in high
frequency performance. Fairchild has evaluation boards to
use as a guide for high frequency layout and as aid in device
testing and characterization. Follow the steps below as a
basis for high frequency layout:
• Include 6.8
µF and 0.01µF ceramic capacitors
• Place the 6.8
µF capacitor within 0.75 inches of
the power pin
• Place the 0.01
µF capacitor within 0.1 inches of
the power pin
• 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 6 for
more information.
Evaluation Board Information
The following evaluation boards are available to aid in the
testing and layout of this device:
Evaluation board schematics and layouts are shown in Figure 5
