BASIC APPLICATION DESCRIPTION
PT2308P is a low power amplifier which operates with a 5V input voltage, it can be used to drive
regular earphones or low power speakers with a load resistance of 8ohm or higher. The operation
mechanics is much like the typical OPAMP. (The picture below shows the basic application circuit of
PT2308P as an inverted amplifier).

1. Gain Settings
The inverted amplifier’s amplification is equal to the ratio between R2 and R1 (Av= -(R2÷R1)).
Please take note that the maximum supply voltage for the PT2308P is 5V, voltage gain setting
should depend on the input level amplitude; too much voltage gain may increase the chance of
causing clipping at the output.
2. VREF
Because the PT2308P operates with a single power source, to ensure the best output performance,
the suggested value for VREF is 1/2 VDD.
