6 W hi-fi audio power amplifier TDA2614
Notes to the characteristics
1. V
P
= 24 V; R
L
= 8 Ω; T
amb
= 25 °C; f = 1 kHz; asymmetrical power supply I
MUTE
< 30 µA. See Fig.5
2. The power bandwidth is measured at an output power of P
O max
− 3 dB.
3. The noise output voltage (RMS value) is measured at R
S
= 2 kΩ, unweighted (20 Hz to 20 kHz).
4. The ripple rejection is measured at R
S
= 0 and f = 100 Hz to 20 kHz, at a ripple voltage of 200 mV. With symmetrical
power supplies, the ripple (200 mV) is applied in phase to the positive and the negative supply rails.
With asymmetrical power supplies, the ripple rejection is measured at f = 1 kHz.

7. The internal network at pin 2 is a resistor devider 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.
