INTEGRATED CIRCUITS DATA SHEET TDA1524A Stereo-tone/volume control circuit Product specification File under Integrated Circuits, IC01 September 1987 Philips Semiconductors Product specification Stereo-tone/volume control circuit TDA1524A GENERAL DESCRIPTION The device is designed as an active stereo-tone/volume control for car radios, TV receivers and mains-fed equipment. It includes functions for bass and treble control, volume control with built-in contour (can be switched off) and balance. All these functions can be controlled by d.c. voltages or by single linear potentiometers. Features * Few external components necessary * Low noise due to internal gain * Bass emphasis can be increased by a double-pole low-pass filter * Wide power supply voltage range.

OUTLINE VERSION REFERENCES IEC JEDEC EIAJ ISSUE DATE 93-10-14 95-01-23 SOT102-1 September 1987 EUROPEAN PROJECTION 15 Philips Semiconductors Product specification Stereo-tone/volume control circuit TDA1524A The device may be mounted up to the seating plane, but the temperature of the plastic body must not exceed the specified maximum storage temperature (Tstg max). If the printed-circuit board has been pre-heated, forced cooling may be necessary immediately after soldering to keep the temperature within the permissible limit. SOLDERING Introduction There is no soldering method that is ideal for all IC packages. Wave soldering is often preferred when through-hole and surface mounted components are mixed on one printed-circuit board. However, wave soldering is not always suitable for surface mounted ICs, or for printed-circuits with high population densities. In these situations reflow soldering is often used. Repairing soldered joints Apply a low voltage soldering iron (less than 24 V) to the lead(s) of the package, below the seating plane or not more than 2 mm above it. If the temperature of the soldering iron bit is less than 300 C it may remain in contact for up to 10 seconds. If the bit temperature is between 300 and 400 C, contact may be up to 5 seconds. This text gives a very brief insight to a complex technology. A more in-depth account of soldering ICs can be found in our "IC Package Databook" (order code 9398 652 90011). Soldering by dipping or by wave The maximum permissible temperature of the solder is 260 C; solder at this temperature must not be in contact with the joint for more than 5 seconds. The total contact time of successive solder waves must not exceed 5 seconds.
