GENERAL DESCRIPTION  
FEATURES  
The SGM8557-1 (single), SGM8557-3 (single with  
shutdown), SGM8557-2 (dual) and SGM8557-5 (dual  
with shutdown) are low noise, high precision CMOS  
operational amplifiers that provide a high output current  
of 240mA, rail-to-rail output operation from a range of  
2.7V to 5.5V single supply. The SGM8557-3/5 are both  
available with shutdown pins that drive the output  
voltage low.  
Output Drive Capability: 240mA  
Low Input Offset Voltage: 5μV (MAX)  
Low Input Offset Voltage Drift: 27nV/(TYP)  
Low Noise: 30nV/ Hz at 1kHz  
Gain-Bandwidth Product: 15MHz  
High Slew Rate: 7V/μs  
High Open-Loop Gain (RL = 2kΩ): 144dB  
Power Supply Rejection Ratio: 120dB  
Over-Temperature Protection  
The SGM8557-1/2/3/5 offer low input offset voltage,  
low input offset voltage drift and high output current  
drive. These devices also can achieve a high 15MHz  
gain-bandwidth product and a high 7V/μs slew rate.  
No Phase Reversal for Overdriven Inputs  
Rail-to-Rail Input and Output  
Supply Voltage Range: 2.7V to 5.5V  
Quiescent Supply Current:  
The SGM8557-1/2/3/5 are specifically designed to  
drive high current load, such as 32Ω headset, VBIAS of  
RF power amplifier, etc.

ESD Susceptibility  
This integrated circuit can be damaged if ESD protections are  
not considered carefully. SGMICRO recommends that all  
integrated circuits be handled with appropriate precautions.  
Failureto observe proper handlingand installation procedures  
can cause damage. ESD damage can range from subtle  
performance degradation tocomplete device failure. Precision  
integrated circuits may be more susceptible to damage  
because even small parametric changes could cause the  
device not to meet the published specifications.

DISCLAIMER  
SG Micro Corp reserves the right to make any change in  
circuit design, or specifications without prior notice.  
OVERSTRESS CAUTION  
Stresses beyond those listed in Absolute Maximum Ratings  
may cause permanent damage to the device. Exposure to  
absolute maximum rating conditions for extended periods  
may affect reliability. Functional operation of the device at any  
conditions beyond those indicated in the Recommended  
Operating Conditions section is not implied.

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.  
Cancel Input Capacitance  
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.

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)  
Input Current-Limit Protection  
Driving Capacitive Loads  
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.  
The SGM8557-1/2/3/5 are 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.

Rail-to-Rail Output  
The SGM8557-1/2/3/5 support rail-to-rail output operation.  
In single power supply application, for example, when  
+VS = 5V, -VS = GND, 2kΩ load resistor is tied from  
OUT pin to VS/2, the typical output swing range is from  
0.008V to 4.992V.

APPLICATIONS INFORMATION (continued)  
Shutdown Mode and Power-Up  
Power Supply Decoupling and Layout  
The SGM8557-3 and SGM8557-5 are disabled when  
the shutdown pin is pulled low. To disable the amplifier,  
the shutdown supply current drops to 0.3μA (TYP) per  
amplifier. When in shutdown mode the operational  
amplifier output is driven to -VS. Pull the shutdown pin  
high to enable the amplifier. Figure 7 shows the output  
voltage to a shutdown pulse. The SGM8557-1/2/3/5  
typically settle within 5μs after power-up.  
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 8.  
The ceramic capacitors should be placed as close as  
possible to +VS and -VS power supply pins.  
When exiting shutdown mode, a 10μs delay-time can  
be added before the amplifier’s output become active  
(Figure 7).
