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.
