APPLICATION NOTESPower Supply Bypassing and Layout
The RS07 operates from either a single 5V to 36V supply or dual ±2.5V to ±18V supplies. For single-supply
operation, bypass the power supply V+ with a 0.1μF ceramic capacitor which should be placed close to the V+pin. For dual-supply operation, both the V+ and the V- supplies should be bypassed to ground with separate
0.1μF ceramic capacitors. 10μF tantalum capacitor can be added for better performance.
Good PC board layout techniques optimize performance by decreasing the amount of stray capacitance at theoperational amplifier’s inputs and output. To decrease stray capacitance, minimize trace lengths and widths byplacing external components as close to the device as possible. Use surface-mount components wheneverpossible.
For the operational amplifier, soldering the part to the board directly is strongly recommended. Try to keep thehigh frequency current loop area small to minimize the EMI (electromagnetic interference).

Figure 13. Amplifier with Bypass Capacitors

GroundingA ground plane layer is important for RS07 circuit design. The length of the current path in an inductive groundreturn will create an unwanted voltage noise. Broad ground plane areas will reduce the parasitic inductance.

Input-to-Output Coupling
To minimize capacitive coupling, the input and output signal traces should not be in parallel. This helps reduce
unwanted positive feedback.

Differential Amplifier
The circuit shown in Figure 14 performs the difference function. If the resistor ratios are equal (R4/R3 = R2/R1),
then VOUT = (VP - VN) × R2/R1 + VREF.

Active Low-Pass Filter
The low-pass filter shown in Figure 16 has a DC gain of (-R2/R1) and the -3dB corner frequency is 1/2πR2C.
Make sure the filter bandwidth is within the bandwidth of the amplifier. Feedback resistors with large values cancouple with parasitic capacitance and cause undesired effects such as ringing or oscillation in high-speed
amplifiers. Keep resistor values as low as possible and consistent with output loading consideration.
