50 W high performance hi-fi amplifier

TDA1514A

Notes to the characteristics

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

Ω.

6. The quiescent current into pin 2 has an impact on the mute time.

7. Without bootstrap.
