| 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 4 load (THD = 10%, VS = 18V, f = 1kHz) and up to 32W into an 8 load (THD = 10%, VS = 22V, f = 1kHz). Moreover, the NTE7169 delivers typically 50W music power into a 4 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 = 8, f = 100Hz to 15kHz) make the device most suitable for both HiFi and high class TV sets.
