The devices are designed for use in TV and monitors, but are also suitable for battery-fed portable recorders and radios. • Few external components • Mute mode • Thermal protection • Short-circuit proof • No switch-on and switch-off clicks Missing Current Limiter (MCL) • Good overall stability A MCL protection circuit is built-in. The MCL circuit is activated when the difference in current between the output terminal of each amplifier exceeds 100 mA (typical 300 mA). This level of 100 mA allows for headphone applications (single-ended). • Low power consumption • Low HF radiation • ESD protected on all pins.

For portable applications there is a trend to decrease the supply voltage, resulting in a reduction of output power at conventional output stages. Using the BTL principle increases the output power. FUNCTIONAL DESCRIPTION The TDA7053A and TDA7053AT are stereo output amplifiers with two DC volume control stages, designed for TV and monitors, but also suitable for battery-fed portable recorders and radios. The maximum gain of the amplifier is fixed at 40.5 dB. The DC volume control stages have a logarithmic control characteristic. Therefore, the total gain can be controlled from +40.5 to −33 dB. In conventional DC volume control circuits the control or input stage is AC coupled to the output stage via external capacitors to keep the offset voltage low. If the DC volume control voltage falls below 0.4 V, the device will switch to the mute mode. The two DC volume control stages are integrated into the input stages so that no coupling capacitors are required and a low offset voltage is still maintained. The minimum supply voltage also remains low. • Lower peak value of the supply current The amplifier is short-circuit protected to ground, VP and across the load. A thermal protection circuit is also implemented. If the crystal temperature rises above 150 °C the gain will be reduced, thereby reducing the output power. • The frequency of the ripple on the supply voltage is twice the signal frequency. Special attention is given to switch-on and switch-off clicks, low HF radiation and a good overall stability. The BTL principle offers the following advantages: Consequently, a reduced power supply with smaller capacitors can be used which results in cost reductions. 1997 Jul 15 4 Philips Semiconductors Product specification Stereo BTL audio output amplifier with DC volume control TDA7053A LIMITING VALUES In accordance with the Absolute Maximum Rating System (IEC 134).

The maximum input signal voltage is measured at THD = 1% at the output with a voltage gain of 0 dB. APPLICATION INFORMATION The application diagram is illustrated in Fig.13. To avoid instabilities and too high distortion, the input ground and power ground must be separated as far as possible and connected as close as possible to the IC. Test conditions Tamb = 25 °C unless otherwise specified; VP = 6 V; VDC = 1.4 V; fi = 1 kHz; RL = 8 Ω. The DC volume control can be applied in several ways. Two possible circuits are shown below the main application diagram. The circuits at the control pin will influence the switch-on and switch-off behaviour and the maximum voltage gain. The quiescent current has been measured without load impedance. The output power as a function of the supply voltage has been measured at THD = 10%. The maximum output power is limited by the maximum power dissipation and the maximum available output current. 1997 Jul 15 For single-end applications the output peak current must not exceed 100 mA. At higher output currents the short-circuit protection (MCL) will be active. 9 Philips Semiconductors Product specification Stereo BTL audio output amplifier with DC volume control TDA7053A handbook, full pagewidth (1) 100 nF 220 µF VP = 6 V 5 TDA7053A 16 470 nF input 1 I+i 4 2 (2) Rs = 5 kΩ I−i STABILIZER 13 input 2 Rs = 5 kΩ − TEMPERATURE MCL PROTECTION 12 470 nF + − I−i 6 8 (2) I+i DCvolume 7 signal ground 9 10 + 14 power ground VP = 6 V volume control 1 µF volume control 2, 8 maximum voltage gain 34 dB 1 µF 1 MΩ 56 kΩ 2, 8 maximum voltage gain 40 dB 22 kΩ MBG673 (1) This capacitor can be omitted if the 220 µF electrolytic capacitor is connected close to pin 5.

Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. 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. Preheating is necessary to dry the paste and evaporate the binding agent. Preheating duration: 45 minutes at 45 °C. WAVE SOLDERING 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). Wave soldering techniques can be used for all SO packages if the following conditions are observed: • A double-wave (a turbulent wave with high upward pressure followed by a smooth laminar wave) soldering technique should be used. DIP SOLDERING BY DIPPING OR BY WAVE • The longitudinal axis of the package footprint must be parallel to the solder flow. 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. • The package footprint must incorporate solder thieves at the downstream end. During placement and before soldering, the package must be fixed with a droplet of adhesive. The adhesive can be applied by screen printing, pin transfer or syringe dispensing. The package can be soldered after the adhesive is cured. 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. Maximum permissible solder temperature is 260 °C, and maximum duration of package immersion in solder is 10 seconds, if cooled to less than 150 °C within 6 seconds. Typical dwell time is 4 seconds at 250 °C. REPAIRING SOLDERED JOINTS A mildly-activated flux will eliminate the need for removal of corrosive residues in most applications. 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. REPAIRING SOLDERED JOINTS Fix the component by first soldering two diagonallyopposite end leads. Use only a low voltage soldering iron (less than 24 V) applied to the flat part of the lead. Contact time must be limited to 10 seconds at up to 300 °C. When using a dedicated tool, all other leads can be soldered in one operation within 2 to 5 seconds between 270 and 320 °C. SO REFLOW SOLDERING Reflow soldering techniques are suitable for all SO packages. Reflow soldering requires solder paste (a suspension of fine solder particles, flux and binding agent) to be applied to the printed-circuit board by screen printing, stencilling or pressure-syringe dispensing before package placement. 1997 Jul 15 TDA7053A 13 Philips Semiconductors Product specification Stereo BTL audio output amplifier with DC volume control TDA7053A DEFINITIONS Data sheet status Objective specification This data sheet contains target or goal specifications for product development.
