Typical Applications
As the signal is transmitted through a cable, the high
frequency signal will be attenuated. One way to compensate
this loss is to boost the high frequency gain at the receiver
side.
Level Shifter and Signal Summer
The EL5175 and EL5375 contains two pairs of differential
pair input stages. It makes the inputs all high impedance. To
take advantage of the two high impedance inputs, the
EL5175 and EL5375 can be used as a signal summer to add
two signals together. One signal can be applied to VIN+; the
second signal can be applied to REF and VIN- is ground.
The output is equal to Equation 6:
Also, the EL5175 and EL5375 can be used as a level shifter
by applying a level control signal to the REF input.
