INTEGRATED CIRCUITS DATA SHEET TDA1510AQ 24 W BTL or 2 x 12 W stereo car radio power amplifier Product specification File under Integrated Circuits, IC01 January 1992 Philips Semiconductors Product specification 24 W BTL or 2 x 12 W stereo car radio power amplifier GENERAL DESCRIPTION TDA1510AQ The TDA1510AQ is a class-B integrated output amplifier encapsulated in a 13-lead single in-line (SlL) plastic power package. Developed primarily for car radio application, the device can also be used to drive low impedance loads (down to 1,6 Ω). With a supply voltage (VP) of 14,4 V, an output power of 24 W can be delivered into a 4 Ω Bridge Tied Load (BTL), or when used as a stereo amplifier, 2 × 12 W into 2 Ω or 2 × 7 W into 4 Ω.
