Philips Semiconductors Product specification
6 W hi-fi audio power amplifier TDA2614
Notes to the characteristics
1. VP = 24 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; asymmetrical power supply IMUTE < 30 µA. See Fig.5
2. The power bandwidth is measured at an output power of PO max − 3 dB.
3. The noise output voltage (RMS value) is measured at RS = 2 kΩ, unweighted (20 Hz to 20 kHz).
4. The ripple rejection is measured at RS = 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.
5. VP = 8 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; asymmetrical power supply. See Fig.5
6. ±VP = 12 V; RL = 8 Ω; Tamb = 25 °C; f = 1 kHz; symmetrical power supply IMUTE < 30 µA. See Fig.4
7. The internal network at pin 2 is a resistor devider of typical 4 kΩand 5 kΩto the positive supply rail. At the connection
of the 4 kΩand 5 kΩresistor 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.
