GENERAL DESCRIPTION
TDA1514A
The TDA1514A integrated circuit is a hi-fi power amplifier for use as a building block in radio, tv and other audio applications. The high performance of the IC meets the requirements of digital sources (e.g. Compact Disc equipment). The circuit is totally protected, the two output transistors both having thermal and SOAR protection (see Fig.3). The circuit also has a mute function that can be arranged for a period after power-on with a delay time fixed by external components. The device is intended for symmetrical power supplies but an asymmetrical supply may also be used. Features · High output power · Low harmonic distortion · Low intermodulation distortion · Low offset voltage · Good ripple rejection · Mute/stand-by facilities · Thermal protection · Protected against electrostatic discharge · No switch-on or switch-off clicks · Very low thermal resistance · Safe Operating Area (SOAR) protection.

Considering, for example, a maximum ambient temperature of 50 °C and a maximum junction temperature of 150 °C the total thermal resistance is: 150 50 R th j-a = --------------------- = 5.3 K/W 19 Since the thermal resistance of the SOT131A encapsulation is Rth j-mb < 1 K/W, the thermal resistance required of the heatsink is Rth h-a < 4.3 K/W.

1. Measured with two superimposed signals of 50 Hz and 7 kHz with an amplitude relationship of 4 : 1. 2. The closed loop gain is determined by external resistors (Fig.4, R2 and R3) and is variable between 20 and 46 dB. 3. The input impedance in the test circuit (Fig.4) is determined by the bias resistor R1. 4. The noise output voltage is measured in a bandwidth of 20 Hz to 20 kHz with a source resistance of 2 k. 5. f = 100 Hz; RS = 2 k; ripple voltage = 500 mV(eff) on positive and negative supply. 6. The quiescent current into pin 2 has an impact on the mute time. 7. Without bootstrap.

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. 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. DEFINITIONS Data sheet status Objective specification Preliminary specification Product specification Limiting values
TDA1514A
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. 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.

Limiting values given are in accordance with the Absolute Maximum Rating System (IEC 134). Stress above one or more of the limiting values may cause permanent damage to the device. These are stress ratings only and operation of the device at these or at any other conditions above those given in the Characteristics sections of the specification is not implied. Exposure to limiting values for extended periods may affect device reliability. Application information Where application information is given, it is advisory and does not form part of the specification. LIFE SUPPORT APPLICATIONS These products are not designed for use in life support appliances, devices, or systems where malfunction of these products can reasonably be expected to result in personal injury.
