Description of Operation and Application
Information
Product Description
The EL5129 and EL5329 are fabricated using a high voltage
CMOS process. They exhibit rail to rail input and output
capability and have very low power consumption. When
driving a load of 10K and 12pF, the buffers have a
-3dB bandwidth of 10MHz and exhibit 9V/s slew rate. The
VCOM amplifier has a -3dB bandwidth of 12MHz and exhibit
10V/s slew rate.
Input, Output, and Supply Voltage Range
The EL5129 and EL5329 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 from 4.5V to 16.5V.
The input common-mode voltage range of the EL5129 and
EL5329 within 500mV beyond the supply rails. The output
swings of the buffers and VCOM amplifier typically extend to
within 100mV of the positive and negative supply rails with
load currents of 5mA. Decreasing load currents will extend
the output voltage even closer to each supply rails.
Output Phase Reversal
The EL5129 and EL5329 are immune to phase reversal as
long as the input voltage is limited from VS- -0.5V to VS+
+0.5V. Although the device's output will not change phase,
the input's over-voltage should be avoided. If an input
voltage exceeds supply voltage by more than 0.6V,
electrostatic protection diode placed in the input stage of the
device begin to conduct and over-voltage damage could
occur.
Output Drive Capability
The EL5129 and EL5329 do not have internal short-circuit
protection circuitry. The buffers will limit the short circuit
current to ±120mA and the VCOM amplifier will limit the short
circuit current to ±170mA if the outputs are directly shorted
to the positive or the negative supply. If the output is shorted
indefinitely, the power dissipation could easily increase such
that the part will be destroyed. Maximum reliability is
maintained if the output continuous current never exceeds
±15mA for the buffers and ±100mA for the VCOM amplifier.
These limits are set by the design of the internal metal
interconnections.
The Unused Buffers
It is recommended that any unused buffers should have their
inputs tied to ground plane.
Power Dissipation
With the high-output drive capability of the EL5129 and
EL5329, it is possible to exceed the 125°C “absolute-
maximum junction temperature” under certain load current
conditions. Therefore, it is important to calculate the
maximum junction temperature for the application to
determine if load conditions need to be modified for the
buffer to remain in the safe operating area.
The maximum power dissipation allowed in a package is
determined according to:
where:
TJMAX = Maximum junction temperature
TAMAX = Maximum ambient temperature
θJA = Thermal resistance of the package
PDMAX = Maximum power dissipation in the package
The maximum power dissipation actually produced by an IC
is the total quiescent supply current times the total power
supply voltage, plus the power in the IC due to the loads, or:
when sourcing, and:
when sinking.
where:
i = 1 to total number of buffers
VS = Total supply voltage of buffer and VCOM
ISMAX = Total quiescent current
VOUTi = Maximum output voltage of the application
VOUT = Maximum output voltage of VCOM
ILOADi = Load current of buffer
ILA = Load current of VCOM
If we set the two PDMAX equations equal to each other, we
can solve for the RLOAD's to avoid device overheat. The
package power dissipation curves provide a convenient way
to see if the device will overheat. The maximum safe power
dissipation can be found graphically, based on the package
type and the ambient temperature. By using the previous
equation, it is a simple matter to see if PDMAX exceeds the
device's power derating curves.
