11 / 18 page  11 FN7119.7 May 7, 2007 Applications Information Product Description The EL5111, EL5211, and EL5411 voltage feedback amplifiers are fabricated using a high voltage CMOS process. 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 general- purpose applications. Connected in voltage follower mode and driving a load of 1k Ω, the EL5111, EL5211, and EL5411 have a -3dB bandwidth of 60MHz while maintaining a 75V/µs 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 -40°C to +85°C. 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 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 Ω load connected to GND. The input is a 10VP-P sinusoid. The output voltage is approximately 9.8VP-P. 5V 5V 10µs VS = ±5V, TA = +25°C, AV = 1, VIN = 10VP-P 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. 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. 1V 1V 10µs VS = ±2.5V, TA = +25°C, AV = 1, VIN = 6VP-P FIGURE 28. OPERATION WITH BEYOND-THE-RAILS INPUT Power Dissipation With the high-output drive capability of the EL5111, EL5211, and EL5411 amplifiers, it is possible to exceed the +125°C 'absolute-maximum junction temperature' under certain load current conditions. Therefore, it is important to calculate the maximum junction temperature for the application to determine if load conditions need to be modified for the amplifier to remain in the safe operating area. The maximum power dissipation allowed in a package is determined according to: P DMAX T JMAX T AMAX – θ JA --------------------------------------------- = (EQ. 1) where: •TJMAX = Maximum junction temperature •TAMAX = Maximum ambient temperature • ΘJA = Thermal resistance of the package •PDMAX = Maximum power dissipation in the package EL5111, EL5211, EL5411 |
