Есть фонокорректор от интегральника Ротель 980 на операцтонниках NE5534AN и TL071CP. Сколько вольт было питание в усилителе неизвестно. По даташитам к операционникам известно следующее:
NE5534A
Large supply voltage range: ±3 to ±20V
VS Supply voltage ±22
TL071
Supply voltage, VCC+ (see Note 1) 18 V
Supply voltage, VCC– (see Note 1) –18 V
Differential input voltage, VID (see Note 2) ±30 V
Input voltage, VI (see Notes 1 and 3) ±15 V
NOTES: 1. All voltage values, except differential voltages, are with respect to the midpoint between VCC+ and VCC–.
2. Differential voltages are at IN+ with respect to IN –.
3. The magnitude of the input voltage must never exceed the magnitude of the supply voltage or 15 V, whichever is less.
4. The output may be shorted to ground or to either supply. Temperature and/or supply voltages must be limited to ensure that the
dissipation rating is not exceeded.
Запитываются параллельно. Сколько вольт должно идти на операционники?
Может быть посоветуете конкретную модель транса?
