Dual Audio Power Amplifier, 2W
Description:
The NTE7055 is a dual audio power amplifier in a 14−Lead DIP type package designed for portable
audio sets.
Features:
D Wide Operating Voltage Range: VCC = 3V to 16V
D High Output Power:
PO = 2W at VCC = 12V, RL = 8Ω, THD = 10%
PO = 1.6W at VCC = 9V, RL = 4Ω, THD = 10%
PO = 1.2W at VCC = 9V, RL = 8Ω, THD = 10%
PO = 0.7W at VCC = 6V, RL = 4Ω, THD = 10%
PO = 0.5W at VCC = 6V, RL = 8Ω, THD = 10%
PO = 80mW at VCC = 4.5V, RL = 32Ω, THD = 10%
D High Supply Voltage Rejection: SVR = 45dB
D Low Quiescent Current: ICC = 12mA
D Low Pop Noise at Power ON/OFF
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
