el5220t Intersil Corporation, el5220t Datasheet - Page 13

• Manufacturer Part Number: el5220t
• Description: 12mhz Rail-to-rail Input-output Operational Amplifier
• Manufacturer: Intersil Corporation

Power Supply Bypassing and Printed Circuit
Board Layout
The EL5220T can provide gain at high frequency, so
good printed circuit board layout is necessary for
optimum performance. Ground plane construction is
highly recommended, trace lengths should be as short
as possible and the power supply pins must be well
bypassed to reduce any risk of oscillation.
For normal single supply operation (the V
connected to ground) a 4.7μF capacitor should be
placed from V
capacitor should be connected as close to the amplifier

as possible. One 4.7μF capacitor may be used for
multiple devices. For dual supply operation the same
capacitor combination should be placed at each supply
pin to ground.
It is highly recommended that EL5220T exposed
thermal pad packages should always have the pad
connected to the lowest potential, V
thermal and operating performance. PCB vias should
be placed below the device’s exposed thermal pad to
transfer heat to the V
device.
