They exhibit rail-to-rail input and output capability, are unity gain stable and have low power consumption (2.4mA per amplifier). These features make the EL9211, EL9212, and EL9214 ideal for a wide range of generalpurpose applications. Connected in voltage follower mode and driving a load of 10K, the EL9211, EL9212, and EL9214 have a -3dB bandwidth of 130MHz while maintaining a 115V/s slew rate. The EL9211 is a single amplifier, EL9212 is a dual amplifier, and EL9214 is a quad amplifier. Unused Amplifiers It is recommended that any unused amplifiers in a dual and 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 EL9211, EL9212, and EL9214 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 0.1F ceramic capacitor should be placed from +VS to pin and -VS to pin. A 4.7F tantalum capacitor should then be connected in parallel, placed in the region of the amplifier. One 4.7F 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. Operating Voltage, Input, and Output The EL9211, EL9212, and EL9214 are specified with a single nominal supply voltage from 5V to 13.5V or a split supply with its total range from 5V to 13.5V. Most EL9211, EL9212, and EL9214 specifications are stable over both the full supply range and operating temperatures of -40C to +85C. Parameter variations with operating voltage and/or temperature are shown in the typical performance curves. Short Circuit Current Limit The EL9211, EL9212, and EL9214 will limit the short circuit current to 300mA if the output is directly shorted to the positive or negative supply. If an output is shorted indefinitely, the power dissipation could easily increase such that the device may be damaged. Maximum reliability is maintained if the output continuous current never exceeds 65mA. This limit is set by the design of the internal metal interconnects. Output Phase Reversal The EL9211, EL9212, and EL9214 are immune to phase reversal as long as the input voltage is limited from -VS -0.5V to +VS +0.5V. Although the device's output will not change phase, the input's over-voltage should be avoided. If an input voltage exceeds supply voltage by more than 0.6V, electrostatic protection diodes placed in the input stage of the device begin to conduct and over-voltage damage could occur.
