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)
