... Data Sheet 60MHz Rail-to-Rail Input-Output Op Amp The EL5211A is a low power, high voltage, rail-to-rail input- output amplifier containing two amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 2.5mA per amplifier, the EL5211A has a bandwidth of 60MHz (-3dB) and provides common-mode input ability beyond the supply rails, as well as rail-to-rail output capability ...

... FIGURE 27. OPERATION WITH RAIL-TO-RAIL INPUT AND OUTPUT Short Circuit Current Limit The EL5211A will limit the short circuit current to ±110mA if the output is directly shorted to the positive or the negative supply output is shorted indefinitely, the power dissipation could easily increase such that the device may be damaged. ...

... Output Phase Reversal The EL5211A is immune to phase reversal as long as the input voltage is limited from V - -0. +0.5V. Figure 28 shows photo of the output of the device with the input voltage driven beyond the supply rails. Although the device's output will not change phase, the input's overvoltage should be avoided input voltage exceeds supply voltage by more than 0 ...

... Power Supply Bypassing and Printed Circuit Board Layout The EL5211A 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 ...
