Description of Operation and Application
Information
Product Description
The EL5524, EL5624, EL5724, and EL5824 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 12MHz and exhibit 18V/µs
slew rate. The V
35MHz and exhibit 80V/µs slew rate.
Input, Output, and Supply Voltage Range
The EL5524, EL5624, EL5724, and EL5824 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 EL5524,
EL5624, EL5724, and EL5824 extends 500mV beyond the
supply rails. The output swings of the buffers and V
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 EL5524, EL5624, EL5724, and EL5824 are immune to
phase reversal as long as the input voltage is limited from
V
change phase, the input's overvoltage 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 overvoltage damage could
occur.

Choice of Feedback Resistor and Gain Bandwidth
Product for V
For applications that require a gain of +1, no feedback
resistor is required. Just short the output pin to the inverting
input pin. For gains greater than +1, the feedback resistor
forms a pole with the parasitic capacitance at the inverting
input. As this pole becomes smaller, the amplifier's phase
margin is reduced. This causes ringing in the time domain
and peaking in the frequency domain. Therefore, R
some maximum value that should not be exceeded for
optimum performance. If a large value of R
small capacitor in the few Pico farad range in parallel with R
can help to reduce the ringing and peaking at the expense of
reducing the bandwidth.
As far as the output stage of the amplifier is concerned, the
output stage is also a gain stage with the load. R
appear in parallel with R
combination gets smaller, the bandwidth falls off.
Consequently, R
be exceeded for optimum performance. For gain of +1, R
0 is optimum. For the gains other than +1, optimum
response is obtained with R

following equation:

Output Drive Capability
The EL5524, EL5624, EL5724, and EL5824 do not have
internal short-circuit protection circuitry. The buffers will limit
the short circuit current to ±120mA and the V
