Audio Power Amplifier, 32W

Description:

The NTE7169 is a monolithic integrated circuit in a 5 - Lead TO220 type package intended for use as

an audio class AB audio amplifier. Thanks to its high power capability, the NTE7169 is able to provide

up to 35W true RMS power into a 4Ω load (THD = 10%, VS = ±18V, f = 1kHz) and up to 32W into an

8Ω load (THD = 10%, VS = ±22V, f = 1kHz). Moreover, the NTE7169 delivers typically 50W music

power into a 4Ω load over 1sec at VS = 22.5V, f = 1kHz. The high power and very low harmonic and

crossover distortion (THD = 0.05% Typ., @ VS = ±22V, PO = 0.1 to 15W, RL = 8Ω, f = 100Hz to 15kHz)

make the device most suitable for both HiFi and high class TV sets.
