3 / 21 page Philips Semiconductors TDA8945S 15 W mono BTL audio amplifier Product specification Rev. 02 — 7 April 2000 3 of 21 9397 750 06866 © Philips Electronics N.V. 2000. All rights reserved. 7. Pinning information 7.1 Pinning 7.2 Pin description 8. Functional description The TDA8945S is a mono BTL audio power amplifier capable of delivering 15 W output power to an 8 Ω load at THD = 10%, using an 18 V power supply and an external heatsink. The voltage gain is fixed at 32 dB. With the three-level MODE input the device can be switched from ‘standby’ to ‘mute’ and to ‘operating’ mode. The TDA8945S outputs are protected by an internal thermal shutdown protection mechanism and a short-circuit protection. Fig 2.
