APPLICATION INFORMATION
Single-Supply Stereo Headphone Driver
A single-supply stereo headphone driver is shown in
Figure 1 as an example to explain the simplified design
procedure.
Bridge Amplifier
A bridge amplifier circuit which can provide 200mW at
3V is shown in Figure 2. Due to differential output, this
structure eliminates the large coupling capacitors in
Figure 1. The voltage gain is 10V/V and the gain can be
changed by changing R2.

APPLICATIONS INFORMATION (continued)
Cancel Input Capacitance
Input Current-Limit Protection
The CIN (20pF TYP) at inverting input pin will generate
a pole at frequency (2πR′CIN)-1, where R′ is the parallel
combination of the gain-setting resistor for the inverting
or non-inverting amplifier in Figure 3. If the pole-frequency
is less than or comparable to the unity-gain bandwidth
(15MHz), the phase margin will be reduced, ringing in
the step response or sustained oscillation will be
generated. To cancel this pole, CF is used to compensate
CIN in Figure 3. Equation 3 gives the CF feedback
capacitance.
For ESD diode clamping protection, when the current
flowing through ESD diode exceeds the maximum
rating value, the ESD diode and amplifier will be
damaged, so current-limit protection will be added in
some applications. One resistor is selected to limit the
current not to exceed the maximum rating value. In
Figure 4, a series input resistor is used to limit the input
current to less than 10mA, but the drawback of this
current-limit resistor is to contribute thermal noise at the
amplifier input. If this resistor must be added, its value
must be selected as small as possible.

APPLICATIONS INFORMATION (continued)
Driving Capacitive Loads
Power Supply Decoupling and Layout
The SGM8604-2XTDU8G is designed for unity-gain
stable for capacitive load up to 780pF. In Figure 5, it
shows the transient response with capacitive load (CL).
If greater capacitive load must be driven in application,
the circuit in Figure 6 can be used. In this circuit, the IR
drop voltage generated by RISO is compensated by
feedback loop.
A clean and low noise power supply is very important in
amplifier circuit design, besides of input signal noise,
the power supply is one of important source of noise to
the amplifiers through +VS and -VS pins. Power supply
bypassing is an effective method to clear up the noise
at power supply, and the low impedance path to ground
of decoupling capacitor will bypass the noise to GND.
In application, 10μF ceramic capacitor paralleled with
0.1μF or 0.01μF ceramic capacitor is used in Figure 7.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.
