Applications Information
Product Description
The EL5220T is a high voltage rail-to-rail input-output
amplifier with low power consumption. The EL5220T
contains two amplifiers. Each amplifier exhibits beyond
the rail input capability, rail-to-rail output capability,
and is unity gain stable.
The EL5220T features a slew rate of 12V/μs. Also, the
device provides common mode input capability beyond
the supply rails, rail-to-rail output capability, and a
bandwidth of 12MHz (-3dB). This enables the
amplifiers to offer maximum dynamic range at any
supply voltage.
Operating Voltage, Input and Output
Capability
The EL5220T can operate on a single supply or dual
supply configuration. The EL5220T operating voltage
ranges from a minimum of 4.5V to a maximum of 19V.
This range allows for a standard 5V (or ±2.5V) supply
voltage to dip to -10%, or a standard 18V (or ±9V) to
rise by +5.5% without affecting performance or
reliability.
The input common-mode voltage range of the EL5220T
extends 500mV beyond the supply rails. Also, the
EL5220T is immune to phase reversal. However, if the
common mode input voltage exceeds the supply voltage
by more than 0.5V, electrostatic protection diodes in the
input stage of the device begin to conduct. Even though
phase reversal will not occur, to maintain optimal
reliability it is suggested to avoid input overvoltage
conditions. Figure 30 shows the input voltage driven
500mV beyond the supply rails and the device output
swinging between the supply rails.
The EL5220T output typically swings to within 50mV 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 31
shows the input and output waveforms for the device in
a unity-gain configuration. Operation is from ±5V
supply with a 10kΩ load connected to GND. The input is
a 10VP-P sinusoid and the output voltage is
approximately 9.9VP-P.
Refer to the “Electrical Specifications” Table beginning
on page 3 for specific device parameters. Parameter
variations with operating voltage, loading and/or
temperature are shown in the “Typical Performance
Output Current
The EL5220T is capable of output short circuit currents
of 200mA (source and sink), and the device has
built-in protection circuitry which limits the output
current to ±200mA (typical).
To maintain maximum reliability the continuous output
current should never exceed ±65mA. This ±65mA limit
is determined by the characteristics of the internal
metal interconnects. Also, see “Power Dissipation” on
page 12 for detailed information on ensuring proper
device operation and reliability for temperature and
load conditions.
Unused Amplifiers
It is recommended that any unused amplifiers 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.
Thermal Shutdown
The EL5220T has a built-in thermal protection which
ensures safe operation and prevents internal damage
to the device due to overheating. When the die
temperature reaches +165°C (typical) the device
automatically shuts OFF the outputs by putting them in
a high impedance state. When the die cools by +15°C
