Applications Information
Product Description
The EL5220C and EL5420C voltage feedback amplifi-
ers are fabricated using a high voltage CMOS process.
They exhibit rail-to-rail input and output capability, they
are unity gain stable, and have low power consumption
(500A per amplifier). These features make the
EL5220C and EL5420C ideal for a wide range of gen-
eral-purpose applications. Connected in voltage follower
mode and driving a load of 10k
and 12pF, the
EL5220C and EL5420C have a -3dB bandwidth of
12MHz while maintaining a 10V/s slew rate. The
EL5220C is a dual amplifier while the EL5420C is a
quad amplifier.
Operating Voltage, Input, and Output
The EL5220C and EL5420C 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
EL5220C and EL5420C 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 EL5220C
and EL5420C extends 500mV beyond the supply rails.
The output swings of the EL5220C and EL5420C typi-
cally extend to within 80mV 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 10k
load
connected to GND. The input is a 10VP-P sinusoid. The
output voltage is approximately 9.985VP-P.

Output
Short Circuit Current Limit
The EL5220C and EL5420C 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. Maximum reli-
ability is maintained if the output continuous current
never exceeds ±30 mA. This limit is set by the design of
the internal metal interconnects.
Output Phase Reversal
The EL5220C and EL5420C 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
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 over-
voltage damage could occur.
