Typical Applications
FIGURE 25. TWISTED PAIR CABLE RECEIVER
FIGURE 26. COMPENSATED LINE RECEIVER
As the signal is transmitted through a cable, the high
frequency signal will be attenuated. One way to compensate
for this loss is to boost the high frequency gain at the
receiver side.
Level Shifter and Signal Summer
The EL5172 and EL5372 contains two pairs of differential
pair input stages, which make sure that the inputs are all
high impedance inputs. To take advantage of the two high
impedance inputs, the EL5172 and EL5372 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 EL5172 and EL5372 can be used as a level shifter
by applying a level control signal to the REF input.
