EL5211A ® Data Sheet June 15, 2005 60MHz Rail-to-Rail Input-Output Op Amp Features The EL5211A is a low power, high voltage, rail-to-rail inputoutput 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. This enables the EL5211A to offer maximum dynamic range at any supply voltage. • 60MHz -3dB bandwidth The EL5211A also features fast slewing and settling times, as well as a high output drive capability of 65mA (sink and source). These features make the EL5211A ideal for high speed filtering and signal conditioning application. Other applications include battery-powered, portable devices and anywhere low power consumption is important. • Rail-to-rail output swing The EL5211A is available in the 8-pin HMSOP package, features a standard operational amplifier pinout, and is specified for operation over a temperature range of -40°C to +85°C. • TFT-LCD panels • Supply voltage = 4.5V to 16.5V • Low supply current (per amplifier) = 2.5mA • High slew rate = 75V/µs • Unity-gain stable • Beyond the rails input capability • ±110mA output short current • Pb-free plus anneal available (RoHS compliant) Applications • VCOM amplifiers • Drivers for A-to-D converters • Data acquisition Ordering Information PART NUMBER (See Note) FN6143.0 • Video processing PACKAGE (Pb-Free) TAPE & REEL PKG.

It exhibits rail-to-rail input and output capability, is unity gain stable, and has low power consumption (2.5mA per amplifier). These features make the EL5211A ideal for a wide range of general-purpose applications. Connected in voltage follower mode and driving a load of 1kΩ, the EL5211A has a -3dB bandwidth of 60MHz while maintaining a 75V/µs slew rate. The EL5211A is a dual amplifier. 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 1kΩ load connected to GND. The input is a 10VP-P sinusoid. The output voltage is approximately 9.8VP-P. 5V 10µs INPUT Applications Information The EL5211A is 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 EL5211A 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 EL5211A extends 500mV beyond the supply rails. The output swings of the EL5211A typically extend to within 100mV of positive and negative supply rails with load currents of 5mA. Decreasing load currents will extend the output voltage 9 5V VS=±5V TA=25°C AV=1 VIN=10VP-P OUTPUT Operating Voltage, Input, and Output 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. 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 FN6143.0 June 15, 2005 EL5211A continuous current never exceeds ±65mA. This limit is set by the design of the internal metal interconnects. Output Phase Reversal The EL5211A is 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. when sourcing, and: P DMAX = Σi [ V S × I SMAX + ( V OUT i – V S - ) × I LOAD i ] when sinking, where: • i = 1 to 2 for dual and 1 to 4 for quad • VS = Total supply voltage • ISMAX = Maximum supply current per amplifier • VOUTi = Maximum output voltage of the application • ILOADi = Load current 1V 10µs VS=±2.5V TA=25°C AV=1 VIN=6VP-P 1V If we set the two PDMAX equations equal to each other, we can solve for RLOADi to avoid device overheat. Figures 29 and 30 provide a convenient way to see if the device will overheat. The maximum safe power dissipation can be found graphically, based on the package type and the ambient temperature. By using the previous equation, it is a simple matter to see if PDMAX exceeds the device's power derating curves. To ensure proper operation, it is important to observe the recommended derating curves shown in Figures 29 and 30. FIGURE 28. OPERATION WITH BEYOND-THE-RAILS INPUT With the high-output drive capability of the EL5211A amplifier, it is possible to exceed the 125°C 'absolutemaximum 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.

PACKAGE POWER DISSIPATION vs AMBIENT TEMPERATURE 10 FN6143.0 June 15, 2005 EL5211A 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. 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. For normal single supply operation, where the VS- pin is connected to ground, a 0.1µF ceramic capacitor should be placed from VS+ to pin to VS- pin. A 4.7µF tantalum capacitor should then be connected in parallel, placed in the region of the amplifier. One 4.7µF 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.
