Voltage Follower Module Supports 5MHz Gain Bandwidth for Buffering Isolation Impedance Matching

Description:
The voltage follower module supports high input impedance and low output resistance.

Main Uses:
1. Buffering
To a certain extent, it can avoid the signal loss caused by high output impedance and small input impedance of the next stage.

2. Isolation
Because the voltage follower has high input impedance and low output impedance, it presents a high-impedance state to the upper circuit and a low-impedance state to the next circuit. Thus, it is often used in the intermediate stage to isolate the front and rear circuits and eliminate the mutual influence between them.

3. Impedance matching and improving load capacity
The characteristics of high input impedance and low impedance output of the common circuit make it play a role in impedance matching in the circuit, which can make the amplification circuit of the latter stage work better.

Design Advantages:
1. MLCC + tantalum capacitor decoupling combination
The decoupling capacitor effectively prevents parasitic oscillations caused by the circuit passing through the positive feedback path formed by power supply. The decoupling capacitor of MLCC and tantalum capacitor is the main way to solve power supply noise. This is very effective in increasing the response speed of transient currents and reducing the impedance of power supply distribution system. This reduces the impedance of power supply system, mitigating sound and reducing noise.

2. PCB heat dissipation
The high-density use of vias in the copper area of the PCB forms an array to improve longitudinal Z heat dissipation and allow the components on the heating surface to cool down quickly. This can effectively avoid the concentration of hot spots on the PCB, and reduce the on-chip reference drift caused by the temperature rise of the chip.

Application:

Stacking Mode:
The voltage follower module can be fixed by copper pillars to plug into a power supply module in a wiring-free way. This greatly facilitates testing and is very helpful for verification tests.

Modules can also be stacked with copper pillars to share a single power supply unit. This flexible design allows for the elimination of wiring cumbersomeness for multiple modules.
