The TDA1514A is a high performance audio power amplifier IC
The document is a preliminary specification sheet for the TDA1514A, an integrated circuit designed as a building block for radio, TV, and other audio applications. It features high output power (up to 50W), low offset voltage, and comprehensive protection mechanisms including thermal, SOAR, short-circuit, and electrostatic discharge protection.
| Output power (THD = -60 dB, Vp=+23V, RL=4Ω) | 50 W |
|---|---|
| Supply voltage range | +9 to +30 V |
| Total quiescent current (typical) | 60 mA |
| Signal plus noise-to-noise ratio | -82 dB |
| Supply voltage ripple rejection (100 Hz) | -72 dB |
| Operating ambient temperature range | See Fig.2 |
The device can deliver 50W with a supply voltage of +23V and a load resistance of 4Ω.
Yes, the circuit has thermal protection on both output transistors.
It uses a Q-lead SIL plastic power package, designated as SOT131A.
