| (R) EL5111, EL5211, EL5411 Data Sheet May 14, 2003 FN7119.1 PRELIMINARY 60MHz Rail-to-Rail Input-Output Op Amps The EL5111, EL5211, and EL5411 are low power, high voltage rail-to-rail input-output amplifiers. The EL5111 represents a single amplifier, the EL5211 contains two amplifiers, and the EL5411 contains four amplifiers. Operating on supplies ranging from 5V to 15V, while consuming only 2.5mA per amplifier, the EL5111, EL5211, and EL5411 have a bandwidth of 60MHz (-3dB). They also provide common mode input ability beyond the supply rails, as well as rail-to-rail output capability. This enables these amplifiers to offer maximum dynamic range at any supply voltage. The EL5111, EL5211, and EL5411 also feature fast slewing and settling times, as well as a high output drive capability of 65mA (sink and source). These features make these amplifiers ideal for high speed filtering and signal conditioning application. Other applications include battery power, portable devices, and anywhere low power consumption is important. The EL5111 is available in 5-pin TSOT and 8-pin HMSOP packages. The EL5211 is available in 8-pin MSOP and 8-pin HMSOP packages. The EL5411 is available in space-saving 14-pin TSSOP and 14-pin HTSSOP packages. All feature a standard operational amplifier pinout. These amplifiers operate over a temperature range of -40C to +85C.

They exhibit rail-to-rail input and output capability, are unity gain stable and have low power consumption (2.5mA per amplifier). These features make the EL5111, EL5211, and EL5411 ideal for a wide range of generalpurpose applications. Connected in voltage follower mode and driving a load of 1k, the EL5111, EL5211, and EL5411 have a -3dB bandwidth of 60MHz while maintaining a 75V/s slew rate. The EL5111 is a single amplifier, the EL5211 a dual amplifier, and the EL5411 a quad amplifier. Operating Voltage, Input, and Output The EL5111, EL5211, and EL5411 are specified with a single nominal supply voltage from 5V to 15V or a split supply with its total range from 5V to 15V. Correct operation is guaranteed for a supply range of 4.5V to 16.5V. Most EL5111, EL5211, and EL5411 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. The input common-mode voltage range of the EL5111, EL5211, and EL5411 extends 500mV beyond the supply rails. The output swings of the EL5111, EL5211, and EL5411 typically extend to within 100mV of positive and negative supply rails with load currents of 5mA. Decreasing load 9 EL5111, EL5211, EL5411 currents will extend the output voltage range even closer to the supply rails. Figure 27 shows the input and output waveforms for the device in the unity-gain configuration. Operation is from 5V supply with a 1k load connected to GND. The input is a 10VP-P sinusoid. The output voltage is approximately 9.8VP-P. VS = 5V, TA = 25C, AV = 1, VIN = 10VP-P 5V 10s 1V INPUT VS = 2.5V, TA = 25C, AV = 1, VIN = 6VP-P 1V 10s FIGURE 28. OPERATION WITH BEYOND-THE-RAILS INPUT OUTPUT 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. 5V FIGURE 27. OPERATION WITH RAIL-TO-RAIL INPUT AND OUTPUT Short Circuit Current Limit The EL5111, EL5211, and EL5411 will limit the short circuit current to 180mA if the output is directly shorted to the positive or the 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. Power Supply Bypassing and Printed Circuit Board Layout The EL5111, EL5211, and EL5411 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 to VS- 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. Output Phase Reversal The EL5111, EL5211, and EL5411 are immune to phase reversal as long as the input voltage is limited from VS- -0.5V to VS+ +0.5V. Figure 28 shows a 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. 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 overvoltage damage could occur.
