TDA1557Q
AC CHARACTERISTICS
VP = 14.4 V; RL = 4 Ω; f = 1 kHz; Tamb = 25 °C; unless otherwise specified. See note 1.
Notes to the characteristics
1. All characteristics are measured using the circuit shown in Fig.4
2. The circuit is DC adjusted at VP = 6 to 18 V and AC operating at VP = 8.5 to 18 V
3. At 18 V < VP < 30 V, the DC output voltage ≤ VP/2
4. Conditions: V11 = 0; short-circuit output to GND; switch V11 to MUTE or ON condition (rise time V11 > 10 µs).
5. Frequency response externally fixed.
6. Ripple rejection measured at the output with a source-impedance of 0
Ω (max. ripple amplitude of 2 V) and a
frequency of 100 Hz.
7. Ripple rejection measured at the output with a source-impedance of 0
Ω (max. ripple amplitude of 2 V) and a
frequency between 1 and 10 kHz.
8. Ripple rejection measured at the output with a source-impedance of 0
Ω (max. ripple amplitude of 2 V) and a
frequency between 100 Hz and 10 kHz. Pin 12 is decoupled with two diodes to ground.
9. Noise voltage measured in a bandwidth of 20 Hz to 20 kHz.
10. Noise output voltage independent of RS (Vin = 0).
