General Description
The EL5210C and EL5410C are low power, high voltage rail-to-rail
input-output amplifiers. The EL5210C contains two amplifiers in one
package and the EL5410C contains four amplifiers. Operating on sup-
plies ranging from 5V to 15V, while consuming only 2.5mA per
amplifier, the EL5410C and EL5210C have a bandwidth of 30MHz --
(-3dB). They also provide common mode input ability beyond the sup-
ply rails, as well as rail-to-rail output capability. This enables these
amplifiers to offer maximum dynamic range at any supply voltage.
The EL5410C and EL5210C also feature fast slewing and settling
times, as well as a high output drive capability of 30mA (sink and
source). These features make these amplifiers ideal for high speed fil-
tering and signal conditioning application. Other applications include
battery power, portable devices, and anywhere low power consump-
tion is important.
The EL5410C is available in a space-saving 14-Pin TSSOP package,
as well as the industry-standard 14-Pin SOIC. The EL5210C is avail-
able in the 8-Pin MSOP and 8-Pin SOIC packages. Both feature a
standard operational amplifier pin out. These amplifiers operate over a
temperature range of -40°C to +85°C.

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 1kand 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 1kload
connected to GND. The input is a 10Vp-p sinusoid. The
output voltage is approximately 9.8VP-P.

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
