Information
Product Description
The EL8202, EL8203 and EL8403 are wide bandwidth,
single supply, low power and rail-to-rail output voltage
feedback operational amplifiers. The amplifiers are internally
compensated for closed loop gain of +1 of greater.
Connected in voltage follower mode and driving a 1kΩ load,
the EL8202, EL8203 and EL8403 have a -3dB bandwidth of
500MHz. Driving a 150Ω load, the bandwidth is about
350MHz while maintaining a 600V/us slew rate. The EL8202
is available with a power down pin to reduce power to 30µA
typically while the amplifier is disabled.

Input, Output and Supply Voltage Range
The EL8202, EL8203 and EL8403 have been designed to
operate with a single supply voltage from 3V to 5.0V. Split
supplies can also be used as long as their total voltage is
within 3V to 5.0V. The amplifiers have an input common
mode voltage range from 0.15V below the negative supply
(V
input signal is outside the above specified range, it will cause
the output signal to be distorted.
The output of the EL8202, EL8203 and EL8403 can swing
rail to rail. As the load resistance becomes lower, the ability
to drive close to each rail is reduced. For the load resistor
1kΩ, the output swing is about 4.9V at a 5V supply. For the
load resistor 150Ω, the output swing is about 4.6V.
