Applications Information
Product Description
The EL5120, EL5220, and EL5420 voltage feedback
amplifiers 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
(500μA per amplifier). These features make the EL5120,
EL5220, and EL5420 ideal for a wide range of general-
purpose applications. Connected in voltage follower mode
and driving a load of 10k
and 12pF, the EL5120, EL5220,
and EL5420 have a -3dB bandwidth of 12MHz while
maintaining a 10V/μs slew rate. The EL5120 is a single
amplifier, the EL5220 is a dual amplifier, and the EL5420 is a
quad amplifier.
Operating Voltage, Input, and Output
The EL5120, EL5220, and EL5420 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
EL5120, EL5220, and EL5420 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 EL5120,
EL5220, and EL5420 extends 500mV beyond the supply
rails. The output swings of the EL5120, EL5220, and
EL5420 typically 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 25 shows the input and
