INTEGRATED CIRCUITS DATA SHEET TDA3803A Stereo/dual TV sound decoder circuit Product specification File under Integrated Circuits, IC02 November 1987 Philips Semiconductors Product specification Stereo/dual TV sound decoder circuit TDA3803A GENERAL DESCRIPTION The TDA3803A is a stereo/dual TV sound decoder circuit with static switching for processing two AF signals in TV and VCR equipment. The LOW/HIGH static switching signals control the AF output selector. Two operational amplifiers perform bandpass filtering of the identification signals. Features • Amplification of the two AF input signals by integrated operational amplifiers • Low distortion stereo de-matrix • All operational amplifiers offset compensated • De-emphasis with operational amplifiers, preferably applied to the output terminals • Two output ports each with two channels for headphones and loudspeakers • Dual sound information at one port, each port individually switchable from sound I to sound II and sound II to sound I • Mute function; while mute is active, it is possible to connect an external mono AF input signal to pin 10 appearing at pins 20 to 23. • Identification without additional signals (horizontal etc.) QUICK REFERENCE DATA Supply voltage (pin 13) VP = V13-12 typ. 12 V Supply current (pin 13) IP = I13 typ. 28 mA Pilot carrier amplifier gain control range ∆Gv > 40 dB Vi(rms) = 1 V ILED typ. 12 mA (S+N)/N ≥ 60 dB Crosstalk in stereo mode αS > 40 dB Crosstalk in dual sound mode αDS > 60 dB A.F. input signals; at Gv = 0 dB (r.m.s. value) LED output current Weighted signal-to-noise ratio of the a.f. signal switches (CCIR468/2) PACKAGE OUTLINE 28-lead DIL; plastic (SOT117); SOT117-1; 1996 November 25.

The total contact time of successive solder waves must not exceed 5 seconds. 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. 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. 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). 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. 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 DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
