Pin Description
Applications Information
Product Description
The EL5421 unity gain buffer is fabricated using a high
voltage CMOS process. It exhibits Rail-to-Rail input and
output capability, and has low power consumption (500µA
per buffer). These features make the EL5421 ideal for a wide
range of general-purpose applications. When driving a load
of 10kΩ and 12pF, the EL5421 has a -3dB bandwidth of
12MHz and exhibits 10V/µS slew rate.
Operating Voltage, Input, and Output
The EL5421 is 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 EL5421 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 output swings of the EL5421 typically extend to within
80mV of positive and negative supply rails with load currents

voltage range even closer to the supply rails. Figure 1 shows
the input and output waveforms for the device. Operation is
from ±5V supply with a 10kΩ load connected to GND. The
input is a 10V
