In single power supply application, for example, when +VS = 36V, -VS = GND, 10kΩ load resistor is tied from OUT pin to ground, the typical output swing range is from 0.185V to 35.815V.

If greater capacitive load must be driven in application, the circuit in Figure 1 can be used.

Amplifier Power Supply Bypassing CF _ VIN + Grounding RISO VOUT CL Figure 1. Circuit to Drive Heavy Capacitive Load Power Supply Decoupling and Layout 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 2. The ceramic capacitors should be placed as close as possible to +VS and -VS power supply pins. SG Micro Corp www.sg-micro.com 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 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.
