NTE1724
Integrated Circuit
Audio Power Amplifier, 20W
Description:
This device is a monolithic integrated circuit and a power amplifier designed for HiâFi audio sets and
in a 10 pin single inâline plastic package. NTE1724 can provide 20W (Typ) to 8⦠at 1% THD and ±22V
supply voltage.
Features:
D High Output Power:
20W Typ (VCC = ±22V, Av = 40dB, f = 20Hz to 20kHz, RL = 8â¦, THD = 1%)
20W Typ (VCC = ±22V, Av = 27.5dB, f = 20Hz to 20kHz, RL = 8â¦, THD = 0.5%)
D Low Distortion:
0.02% Typ (VCC = ±22V, Av = 40dB, f = 1kHz, RL = 8â¦, POUT = 5.0W)
0.005% Typ (VCC = ±22V, Av = 27.5dB, f = 1kHz, RL = 8â¦, POUT = 5.0W)
D Wide Frequency Bandwidth: f = 250kHz (â3dB)
