Applications Information
Product Description
The ISL55016 Silicon Bipolar amplifier can match a 75Ω
single-ended source to a 100Ω differential load. This feature
makes the ISL55016 ideal for a wide range of general
purpose applications, such as Satellite TV.
Typical Application Circuit
ISL55016 is a true differential amplifier. Figure 29 shows the
Typical Application Circuit of ISL55016. Pins 2 and 3 are
equivalent.
The ISL55016 can configured so that it is driven with a
single-ended input. If either pin 2 or pin 3 is used as a
single-ended input, the other needs to be connected to an
AC ground. The input is internally matched to 75Ω
single-ended and the output is matched to 50Ω single-ended
or 100Ω differential.

LOAD
The ISL55016 can be used as differential-in and differential-
out as well since pin 2 and pin 3 are equivalent, balanced
inputs.
Balun Function
In many applications of ISL55012, the amplifier will be
followed with a Balun structure to transfer the single-ended
signal to a differential tuner. The ISL55016 will eliminate the
need for an external balun structure and provide significant
savings in BOM cost and PCB real-estate (see Figure 30).
