SGM8634C
550μA, 6MHz, Rail-to-Rail I/O
CMOS Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM8634C is a quad, low voltage, low noise and
low power operational amplifier, whichcan operate from
2.5V to 5.5V single supply, while consuming only
550μA quiescent current per amplifier at 5V.
Input Offset Voltage: 3.5mV (MAX)
High Gain-Bandwidth Product: 6MHz
High Slew Rate: 3.7V/μs
Settling Time to 0.1% with 2V Step: 2.1μs
Overload Recovery Time: 0.9μs
The SGM8634C features a 3.5mV maximum input
offset voltage. The minimum input common mode
voltage is within 0.1V below the negative rail, and the
output swing is rail-to-rail with heavy loads. It exhibits a
high gain-bandwidth product of 6MHz and a slew rate
of 3.7V/μs. These specifications make the operational
amplifier appropriate for various applications.
Low Noise: 12nV/ Hz
√

APPLICATION INFORMATION
Rail-to-Rail Input
Power Supply Decoupling and Layout
When SGM8634 works at the power supply between
2.5V and 5.5V, the input common mode voltage range
is from (-VS) - 0.1V to (+VS) + 0.1V. In Figure 1, the ESD
diodes between the inputs and the power supply rails
will clamp the input voltage not to exceed the rails.
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 amplifier 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 3.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.

Rail-to-Rail Output
The SGM8634 supports rail-to-rail output operation. In
single power supply application, for example, when +VS
= 5V, -VS = GND, 10kΩ load resistor is tied from OUT
pin to ground, the typical output swing range is from
0.015V to 4.985V.

Driving Capacitive Loads
0.1μF
The SGM8634 is designed for unity-gain stable for
capacitive load up to 1000pF. If greater capacitive load
must be driven in application, the circuit in Figure 2 can
be used. In this circuit, the IR drop voltage generated
by RISO is compensated by feedback loop.

Figure 3. Amplifier Power Supply Bypassing
Grounding
RF
CF
In low speed application, one node grounding technique
is the simplest and most effective method to eliminate
the noise generated by grounding. In high speed
application, the general method to eliminate noise is to
use a complete ground plane technique, and the whole
ground plane will help distribute heat and reduce EMI
noise pickup.

Reduce Input-to-Output Coupling
Figure 2. Circuit to Drive Heavy Capacitive Load
To reduce the input-to-output coupling, the input traces
must be placed as far away from the power supply or
output traces as possible. The sensitive trace must not
be placed in parallel with the noisy trace in same layer.
They must be placed perpendicularly in different layers
to reduce the crosstalk. These PCB layout techniques
will help to reduce unwanted positive feedback and
noise.

Active Low-Pass Filter
Typical Application Circuits
The circuit in Figure 6 is a design example of active
low-pass filter, the DC gain is equal to -R2/R1 and the
-3dB corner frequency is equal to 1/2πR2C. In this
design, the filter bandwidth must be less than the
bandwidth of the amplifier, the resistor values must be
selected as low as possible to reduce ringing or
oscillation generated by the parasitic parameters in
PCB layout.
Difference Amplifier
The circuit in Figure 4 is a design example of classical
difference amplifier. If R4/R3 = R2/R1, then VOUT = (VP -
VN) × R2/R1 + VREF
