The TBA820M is a 1.2W audio amplifier with a working voltage range of 3V-16V, and can be used in portable radios, cassette recorders and players.
The TBA820M is a monolithic integrated audio amplifier in an 8‑lead dual‑in‑line plastic package. It is intended for low‑frequency class‑B power amplification in portable radios, cassette recorders, and similar devices, with a wide supply voltage range of 3 V to 16 V.
Key specifications include a typical output power of 2 W at 12 V, low quiescent output voltage around 4 V, input resistance of 5 MΩ, and a closed‑loop voltage gain of 45 dB. Mechanical data for the MINIDIP package and absolute maximum ratings are also provided.
| Supply voltage range | 3 V to 16 V |
|---|---|
| Output power (12 V supply) | 2 W |
