11 / 14 page 11 EL5210C/EL5410C 30MHz Rail-to-Rail Input-Output Op Amps Applications Information Product Description The EL5210C and EL5410C voltage feedback amplifi- ers 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 EL5210C and EL5410C ideal for a wide range of gen- eral-purpose applications. Connected in voltage follower mode and driving a load of 1k Ω and 12pF, the EL5210C and EL5410C have a -3dB bandwidth of 30MHz while maintaining a 33V/µS slew rate. The EL5210C is a dual amplifier while the EL5410C is a quad amplifier. Operating Voltage, Input, and Output The EL5210C and EL5410C 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 EL5210C and EL5410C 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 per- formance curves. The input common-mode voltage range of the EL5210C and EL5410C extends 500mV beyond the supply rails. The output swings of the EL5210C and EL5410C typi- cally 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 1 shows the input and output waveforms for the device in the unity-gain configura- tion. 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. Figure 1. Operation with Rail-to-Rail Input and Output Short Circuit Current Limit The EL5210C and EL5410C will limit the short circuit current to +/-120mA 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. Maxi- mum reliability is maintained if the output continuous current never exceeds +/-30mA. This limit is set by the design of the internal metal interconnects. Output Phase Reversal The EL5210C and EL5410C are immune to phase rever- sal as long as the input voltage is limited from VS- - 0.5V to VS+ +0.5V. Figure 2 shows a photo of the out- put 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 VS=±5V TA=25°C AV=1 VIN=10VP-P 5V 5V 10µ S |
