Application Note 1595
Amplifier Configuration
(Figure 3)
The schematic of the op amp input stage with the
components supplied is shown in Figure 3, with a closed
loop gain of 10V/V. The differential amplifier gain is
expressed in Equation 1:
User-selectable Options
(Figures 3 and 4)
Component pads are included to enable a variety of
user-selectable circuits to be added to the amplifier
inputs, the VREF input, outputs and the amplifier
feedback loops.
V OUT = ( V IN+ – V IN- ) ? ( R F ? R IN ) + V REF
(EQ. 1)
A voltage divider (Figure 3, R18 and R15) can be added
to establish a power supply-tracking common mode
For single-ended input with an inverting gain G = -10V/V,
the IN+ input is grounded and the signal is supplied to the
IN- input. VREF can be connected to a reference voltage
between the V+ and V- supply rails. For non-inverting
operation with G = 11V/V, the IN- input is grounded and
the signal is supplied to the IN+ input. The non-inverting
gain is strongly dependent on any resistance from IN- to
GND. For good gain accuracy, a 0 Ω resistor should be
installed on the empty R5 pad.

reference using the VREF input. The inverting and
non-inverting inputs have additional resistor placements
for adding input attenuation, or to establish input DC
offsets through the VREF pin.
The output (Figure 4) also has additional resistor and
capacitor placements for filtering and loading.
NOTE: Operational amplifiers are sensitive to output
capacitance and may oscillate. In the event of oscillation,
reduce output capacitance by using shorter cables, or
add a resistor in series with the output.
