1pcs TDA3810 Spatial, stereo and and similar items

The TDA3810 is an integrated circuit audio processor designed to provide spatial, stereo, and pseudo-stereo sound effects in radio and television equipment. Key Features Audio Modes: The IC supports three selectable modes: mono/pseudo-stereo, stereo, and spatial stereo (also known as "surround sound" or "widened stereo image"). Inputs/Outputs: It accepts stereo audio signals as input and provides outputs for the left and right channels. It also includes dedicated LED driver outputs to indicate the currently selected mode. Supply Voltage: It operates from a wide supply voltage range, typically 4.5 V to 16.5 V, with a low current consumption of around 7 mA (typical). External Components: The quality and strength of the pseudo-stereo and spatial effects are determined by external components (resistors and capacitors) used in conjunction with the internal operational amplifiers. Low Distortion: It features low total harmonic distortion (typically 0.1% in stereo mode) and high channel separation (typically 70 dB). Reduced Switching Noise: The use of offset-compensated operational amplifiers and a start/stop circuit helps to minimize noise during mode switching and prevent LED flicker. Operating Modes The different modes are selected using control pins (pins 11 and 12): Mode Pin 11 Pin 12 LED Pin 7 (Spatial) LED Pin 8 (Pseudo) Mono pseudo-stereo HIGH LOW off on Spatial stereo HIGH HIGH on off Stereo LOW X (irrelevant) off off Applications The TDA3810 is commonly used in DIY electronics projects
