FUNCTIONAL DESCRIPTION

The TDA2615 is a hi-fi stereo amplifier designed for mains fed applications, such as stereo radio and stereo TV. The circuit is optimally designed for symmetrical power supplies, but is also well-suited to asymmetrical power supply systems.

An output power of 2 × 6W (THD = 0.5%) can be delivered into an 8 Ω load with a symmetrical power supply of ±12 V. The gain is internally fixed at 30 dB, thus offering a low gain spread and a very good gain balance between the two amplifiers (0.2 dB).

A special feature is the input mute circuit. This circuit disconnects the non-inverting inputs when the supply voltage drops below±6 V, while the amplifier still retains its DC operating adjustment. The circuit features suppression of unwanted signals at the inputs, during switch-on and switch-off.

The mute circuit can also be activated via pin 2. When a current of 300 µA is present at pin 2, the circuit is in the mute condition.

The device is provided with two thermal protection circuits. One circuit measures the average temperature of the crystal and the other measures the momentary temperature of the power transistors. These control circuits attack at temperatures in excess of +150 °C, so a crystal operating temperature of max. +150 °C can be used without extra distortion.

With the derating value of 6 K/W, the heatsink can be calculated as follows:

=8Ω and VS= ±12 V, the measured maximum

at R

dissipation is 7.8 W.

Notes

1. VP= ±12 V; RL=8Ω; T

2. The power bandwidth is measured at a maximum output power (P

3. The noise output voltage (RMS value) is measured at RS=2kΩ, unweighted (20 Hz to 20 kHz).

4. The ripple rejection is measured at RS= 0 and fi= 100 Hz to 20 kHz. The ripple voltage (200 mV) is applied in phase to the positive and the negative supply rails. With asymmetrical power supplies, the ripple rejection is measured at fi= 1 kHz.

5. ±VP= 4 V; RL=8Ω; T

6. VP= 24 V; RL=8Ω; T

7. The internal network at pin 2 is a resistor divider of typical 4 kΩ and 5 kΩ to the positive supply rail. At the connection of the 4 kΩ and 5 kΩ resistor a zener diode of typical 6.6 V is also connected to the positive supply rail. The spread of the zener voltage is 6.1 to 7.1 V.
