INTEGRATED CIRCUITS DATA SHEET TDA7052B Mono BTL audio amplifier with DC volume control Product specification Supersedes data of 1996 May 28 1997 Aug 15 NXP Semiconductors Product specification Mono BTL audio amplifier with DC volume control TDA7052B FEATURES GENERAL DESCRIPTION • DC volume control The TDA7052B and TDA7052BT are 1 W and 0.5 W mono Bridge-Tied Load (BTL) output amplifiers with DC volume control. They have been designed for use in TV and monitors, but are also suitable for use in battery-fed portable recorders and radios. • Few external components • Mute mode • Thermal protection • Short-circuit proof • No switch-on and switch-off clicks A Missing Current Limiter (MCL) is built in. The MCL circuit is activated when the difference in current between the output terminal of each amplifier exceeds 100 mA (300 mA typ.). This level of 100 mA allows for headphone applications (single-ended). • Good overall stability • Low power consumption • Low HF radiation • ESD protected on all pins.

The DC volume control stage has a logarithmic control characteristic. Therefore, the total gain can be controlled from 40.5 dB to −33 dB. If the DC volume control voltage falls below 0.4 V, the device will switch to the mute mode. The TDA7052B and TDA7052BT are mono BTL output amplifiers with DC volume control which have been designed for use in TV and monitors but are also suitable for use in battery-fed portable recorders and radios. The amplifier is short-circuit proof to ground, VP and across the load. Also a thermal protection circuit is implemented. If the crystal temperature rises above +150 °C the gain will be reduced, thereby reducing the output power. Special attention is given to switch-on and switch-off clicks, low HF radiation and a good overall stability. In conventional DC volume circuits the control or input stage is AC coupled to the output stage via external capacitors to keep the offset voltage low. In the TDA7052B and TDA7052BT the DC volume control stage is integrated into the input stage so that no coupling capacitors are required. With this configuration, a low offset voltage is maintained and the minimum supply voltage remains low. The BTL principle offers the following advantages: Power dissipation • Lower peak value of the supply current Assume for the TDA7052B that VP = 6 V; RL = 8 Ω. The maximum sine wave dissipation is 0.9 W. The Rth j-a of the package is 100 K/W. Therefore Tamb(max) = 150 − 100 × 0.9 = 60 °C. • The frequency of the ripple on the supply voltage is twice the signal frequency. Consequently, a reduced power supply with smaller capacitors can be used which results in cost reductions. 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. Assume for the TDA7052BT that VP = 6 V; RL = 16 Ω. The maximum sine wave dissipation is 0.46 W. The Rth j-a of the package is 155 K/W. Therefore Tamb(max) = 150 − 155 × 0.46 = 78 °C.

With a load connected to the outputs the quiescent current will increase, the maximum value of this increase being equal to the DC output offset voltage divided by RL. 2. The noise output voltage (RMS value) at f = 500 kHz is measured with RS = 0 Ω and B = 5 kHz. 3. The ripple rejection is measured with RS = 0 Ω and f = 100 Hz to 10 kHz. The ripple voltage VR of 200 mV (RMS value) is applied to the positive supply rail. 4. The noise output voltage (RMS value) is measured with RS = 5 kΩ unweighted. 5. The DC volume control can be configured in several ways. Two possible circuits are shown in Figs 14 and 15. The circuits at the volume control pin will influence the switch-on and switch-off behaviour and the maximum voltage gain. 1997 Aug 15 5 NXP Semiconductors Product specification Mono BTL audio amplifier with DC volume control TDA7052B MBH372 40 MBH373 1 handbook, halfpage handbook, halfpage Gv (dB) 0 Vno (mV) −40 10−1 −80 −120 10−2 0 0.4 0.8 1.2 1.6 V DC 2.0 (V) 0 0.4 0.8 1.2 1.6 2.0 VDC (V) Measured with RS = 5 kΩ unweighted.

Dwell times vary between 50 and 300 seconds depending on heating method. Typical reflow temperatures range from 215 to 250 °C. 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 Aug 15 TDA7052B 13 NXP Semiconductors Product specification Mono BTL audio amplifier with DC volume control TDA7052B DATA SHEET STATUS DOCUMENT STATUS(1) PRODUCT STATUS(2) DEFINITION Objective data sheet Development This document contains data from the objective specification for product development.
