Special features of this device are: 1. Mode select switch 2. Clip detection 3. Short-circuit diagnostic 4. Temperature pre-warning 5. Open-collector outputs 6. Differential inputs. Mode select switch (pin 14) • Standby: low supply current (< 100 µA) • Mute: input signal suppressed • Operating: normal on condition. Since this pin has a very low input current (< 40 µA), a low cost supply switch can be applied. To avoid switch-on plops, it is advisable to keep the amplifier in the mute mode for a period of ≥150 ms (charging the input capacitors at pins 1, 2, 16 and 17). This can be realized by microcontroller control or by an external timing circuit (see Fig.7). Clip detection (pin 4) When clipping occurs at one or more output stages, the dynamic distortion detector becomes active and pin 4 goes low. This information can be used to drive a sound processor or DC volume control to attenuate the input signal and so limit the level of distortion. The output level of pin 4 is independent of the number of channels that are being clipped. The clip detection circuit is disabled in a short-circuit condition, so if a fault condition occurs at the outputs, pin 4 will remain at a high level. The clip detection waveforms are illustrated in Fig.3. |
