DATASHEET and Circuit Diagram

Zener diode is a type of diode whose reverse-breakdown characteristics are controlled precisely during manufacture. It intended specifically for operation in the reverse-breakdown mode primarily as inexpensive voltage references. We introduct you with article about the zener diode mainly in knowing of ‘Zener breakdown’ phenomena, a phenomen that mostly happen in all semiconductor junction diodes.

What you will see in this article are Zener Diode Breakdown Characteristics, Diode-Zener Comparison, and Zener Diode ‘Shunt’ Regulator. Describe you with how the phenomena mechanisms works with an illustrative breakdown characteristics diagram provided, a test circuit to build an idealized-diode equivalent circuit for a Zener diode which allowing both for forward and reverse bias, the circuit application diagram for shunt voltage regulator purpose.

The TPA6110A2 is an ideal option for stereo headphone applications in portable equipment, such as MP3 players,  wireless phones, Internet appliances, voice recorders and CD players. It consists of the TI TPA6110A2 150-mW stereo audio power amplifier IC in a very small MSOP package, along with a small number of other parts mounted on a circuit board that is approximately one and a quarter inches square!

According to the TPA6110A2 datasheet, total harmonic distortion plus noise (THD+N) for 32-Ohm loads is reduced to less than 0.02 percent at 1 kHz and is less than 1 percent across the audio band of 20 Hz to 20 kHz. It includes a list of EVM features, a brief description of the module illustrated with a pictorial diagram, and a list of EVM specifications.
