Applications Information
Product Description
The EL5211T is a high voltage rail-to-rail input-output
amplifier with low power consumption. The EL5211T
contains four amplifiers. Each amplifier exhibits beyond
the rail input capability, rail-to-rail output capability and
is unity gain stable.
The EL5211T features a high slew rate of 100V/μs, and
fast settling time. Also, the device provides common
mode input capability beyond the supply rails, rail-to-rail
output capability, and a bandwidth of 60MHz (-3dB). This
enables the amplifiers to offer maximum dynamic range
at any supply voltage.
Operating Voltage, Input and Output
Capability
The EL5211T can operate on a single supply or dual
supply configuration. The EL5211T 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 EL5211T
extends 500mV beyond the supply rails. Also, the
EL5211T 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 32 shows the input voltage driven
500mV beyond the supply rails and the device output
swinging between the supply rails.
The EL5211T 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 33
shows the input and output waveforms for the device in a
unity-gain configuration. Operation is from ±5V supply
with a 1kΩ 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 EL5211T is capable of output short circuit currents of
300mA (source and sink), and the device has built-in
protection circuitry which limits the output current to
±300mA (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 EL5211T 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 (typical), the device
automatically turns ON the outputs by putting them in a
low impedance (normal) operating state.
