SGM8358
1MHz, 60μA, Rail-to-Rail I/O
CMOS Operational Amplifier
GENERAL DESCRIPTION
FEATURES
The SGM8358 is a dual, low cost, voltage feedback
amplifier. The device can operate from 2.1V to 5.5V
single supply, while consuming only 60μA quiescent
current per amplifier. It provides rail-to-rail input with a
wide input common mode voltage range and rail-to-rail
output voltage swing. This feature makes SGM8358
appropriate for buffering ASIC.

APPLICATION INFORMATION
Rail-to-Rail Input
Power Supply Decoupling and Layout
When SGM8358 works at the power supply between
2.1V 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 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 3.
The ceramic capacitors should be placed as close as
possible to +VS and -VS power supply pins.

Rail-to-Rail Output
The SGM8358 supports rail-to-rail output operation. In
single power supply application, for example, when +VS
= 5V, -VS = GND, 100kΩ load resistor is tied from OUT
pin to VS/2, the typical output swing range is from
0.005V to 4.997V.

0.1μF
The SGM8358 is designed for unity-gain stable for
capacitive load up to 250pF. 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.

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
