Introduction of AD8324ACPZ Line Driver
The AD8324ACPZ is a line driver. It is an affordable cost amplifier that is designed to drive coaxial lines. Its gain is controlled digitally. It can accept an input single-ended or differential signal. More information about differential line drivers is available below. The output is intended to drive a 75Ω load via a 1:1 transformer. The device comes with the sleep mode feature which reduces the quiescent current to 30μA, and an all-power-down feature that reduces the power-down current to 2.5mA. It is powered by only a single 3.3 V power supply.
What does a differential line driver do?
The differential driver can be employed to improve the level of noise-proofing. A differential line driver lets you source or sinks more current than the Totem Pole output. It works using a sinking and source circuit.

How to Use AD8324ACPZ Line Driver?
Why We Use a Line Driver?
In cable modems as well as CATV set-top boxes, high-performance analog circuitry is crucial to the operation. Line drivers may exceed the output voltage capabilities of standard emitter-follower output stages. The line driver ic is an electronic amplifier circuit designed to be used for controlling a load, such as a transmission line. The amplifier’s output resistance can be adjusted to match the resistance of the line.
The line driver ic is a set of transistors that are packaged inside an IC which allows several higher power outputs to be controlled from your low-power project. Since they are just sets of transistors, they are either sinking or sourcing power.
Except as mentioned above, we also see an audio line driver in our life
What is an audio line driver?
Audio line drivers are electronic amplifier circuit that was designed to drive a load, like a transmission line. In the field of analog audio lines, an audio line driver is usually utilized to drive line-level analog signal outputs, like connecting a CD player into an amplified audio speaker.
