The TDA7057 is a stereo BTL (Bridge Tied Load) integrated circuit (IC) designed for audio amplification in low-power applications and has a total of 13 pins.
It is primarily used for amplifying audio signals in small, battery-powered devices such as portable radios, intercoms, TVs, monitors, and other similar applications.
In addition, It is also suitable for driving small speakers, headphones, and other such appliances that do not need high amplification.
TDA7057 Features and Specifications
As with any other IC, it has its unique features and specifications, we highlight some key features and specifications of the TDA7057 below.
Power Output:
The TDA 7057 is a low-power stereo audio amplifier, and its typical output power is relatively low, typically 8 watts per channel totaling 16 watts for the two channels.
Operating Voltage:
The TDA 7057 is designed to operate from a single power supply voltage in the range of 2.0 to 15 volts. This makes it well-suited for battery-powered devices.
Stereo Amplifier:
The TDA 7057 is a stereo (double-channel) audio amplifier, which means it amplifies a dual audio output signal. It can be bridged to produce a mono audio output.
Low Distortion:
It offers relatively low distortion for its power rating, making it suitable for applications where audio quality is important.
Package Type:
The TDA 7057 is typically available in an SIP 13 Pin-type package making it compact and suitable for space-constrained designs.
More Features
Application:
The TDA 7057 is commonly used in portable audio devices, intercom systems, small radio receivers, and other low-power audio amplification applications.
DC volume control:
The volume level of this IC is adjusted by varying the DC voltage that is applied to the amplifier or other relevant components in the audio circuit.
A few external components:
It requires fewer components because its structure has most of the components built inside the IC.
Mute mode:
The 7057 has a mute mode which means you can be able to mute the audio output depending on how the circuit is configured.
Thermal protection:
The 7057 comes with an inbuilt thermal protection mechanism that protects it from overheating.
Short-circuit proof:
In case of a short circuit, the TDA 7057 shuts off due to an inbuilt short circuit-proof mechanism…
No switch-on and switch-off clicks:
There is no audible click when switching this IC on or off. This is a good attribute because it does not interfere with user experience.
Maker: The TDA7057 is made by Philips Electronics a renowned global electronics company.
