... Operating on supplies ranging from 5V to 15V, while consuming only 2.0mA, the EL5128 has a bandwidth of 12MHz (-3dB) and provides common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables the amplifier to offer maximum dynamic range at any supply voltage ...

... FIGURE 28. PACKAGE POWER DISSIPATION vs AMBIENT Power Supply Bypassing and Printed Circuit Board Layout The EL5128 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 ...
