NTE7169
Integrated Circuit
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%, V_S = ±18V, f = 1kHz) and up to 32W into an
8Ω load (THD = 10%, V_S = ±22V, f = 1kHz). Moreover, the NTE7169 delivers typically 50W music
power into a 4Ω load over 1sec at V_S = 22.5V, f = 1kHz. The high power and very low harmonic and
crossover distortion (THD = 0.05% Typ., @ V_S = ±22V, P_O = 0.1 to 15W, R_L = 8Ω, f = 100Hz to 15kHz)
make the device most suitable for both HiFi and high class TV sets.
