9 / 10 page  9 FN6735.0 October 2, 2008 Where: • i = 1 to 2 for dual and 1 to 4 for quad •VS = Total supply voltage •ISMAX = Maximum supply current per amplifier •VOUTi = Maximum output voltage of the application •ILOADi = Load current If we set the two PDMAX equations equal to each other, we can solve for RLOADi to avoid device overheat. Unused Amplifiers It is recommended that any unused amplifiers in a dual and a quad package be configured as a unity gain follower. The inverting input should be directly connected to the output and the non-inverting input tied to the ground plane. Power Supply Bypassing and Printed Circuit Board Layout The ISL24020 can provide gain at high frequency. As with any high-frequency device, good printed circuit board layout is necessary for optimum performance. Ground plane construction is highly recommended, lead lengths should be as short as possible and the power supply pins must be well bypassed to reduce the risk of oscillation. For normal single supply operation, where the VS- pin is connected to ground, a 0.1µF ceramic capacitor should be placed from VS+ to pin to VS- pin. A 4.7µF tantalum capacitor should then be connected in parallel, placed in the region of the amplifier. One 4.7µF capacitor may be used for multiple devices. This same capacitor combination should be placed at each supply pin to ground if split supplies are to be used. ISL24020 |
