GainAmp Signal Coupling
and Configurations
Common op amp configurations include both noninvert-
ing and inverting amplifiers. Figures 3–6 show various
single- and dual-supply circuit configurations. In single-
supply systems, use a resistor-divider to bias the nonin-
verting input. A lowpass filter capacitor from the op amp
input to ground (Figure 5) prevents high-frequency
power-supply noise from coupling into the op amp input.
Dual-supply systems can have ground-referenced sig-
nals DC-coupled into the inverting or noninverting inputs.
Supply Bypassing and Board Layout
All devices in this GainAmp family operate from a +2.5V
to +5.5V single supply or from ±1.25V to ±2.75V dual
supplies. For single-supply operation, bypass the power
supply with a 0.1μF capacitor to ground. For dual sup-
plies, bypass each supply to ground. Bypass with
capacitors as close to the device as possible to mini-
mize lead inductance and noise. A printed circuit board
with a low-inductance ground plane is recommended.
Capacitive-Load Stability
Driving large capacitive loads can cause instability in
most low-power, rail-to-rail output amplifiers. The fixed-
gain amplifiers of this GainAmp family are stable with
capacitive loads up to 100pF. Stability with higher
capacitive loads can be improved by adding an isola-
tion resistor in series with the op amp output, as shown
in Figure 7. This resistor improves the circuit’s phase
margin by isolating the load capacitor from the amplifi-
er’s output. In Figure 8, a 220pF capacitor is driven with
a 100
isolation resistor exhibiting some overshoot but
no oscillation. Figures 9 and 10 show the typical small-
signal pulse responses of GainAmp fixed-gain ampli-
fiers with 47pF and 100pF capacitive loads and no
isolation resistor
