Description
Module with audio amplifier class-D TPA2005D1 from Texas Instruments. Little power loss, that is, small heat generation and longer battery life. It allows you to connect a speaker of 8 Ohms, power 1.4 watts. It has a connector forpotentiometer(10 kOhm) designed to adjust the volume.
The system inputs are differential, protecting input signal from the primary layout, for example, available in our store Arduino Mp3 Shield. The shutdown input ensures that the system is in a low power state when not in use.
Specification
- Power supply: from 2.5 V to 5.5 V
- Power: 1.4 Watts (8 Ohms)
- Class: D
- Fully differentialaudio input
- The input mode low consumption current, with built-in pull-up resistor
- Pads, allowing to solder resistors, changing the gain
- Connector allows you to setthe potentiometer10 kω controlling the gain - volume
Connection
The system has ten pins, the raster is 2.54, to which you can solder standard connectorsgoldpin:
- PWR- module power supply range from 2.5 V to 5.5 V.
- IN- the input signal is connected respectively between terminals + and -.
- OUT- amplified output signal.
- S- shutdown input, for low energy consumption mode - low condition. The outputSby default is pulled up to the supply voltage, when the output is not connected is indicates the normal operation of the module.
- VOL- connectors are used to connect the externalpotentiometer10 kOhm volume control (optional).
A detailed description along with an example of connection can be found inthe instructionson the manufacturer's website.
