NTE1898 & NTE1899
Integrated Circuit
Dual Audio Power Amp, 5.8W (22W BTL)
Description:
The NTE1898 and NTE1899 are dual audio power amplifiers in a 12–Lead SIP type package de-
signed for use as high performance, car–audio power amplifiers in consumer applications. These
devices feature high power, low distortion, and low noise along with various types of protection cir-
cuits. The NTE1899 is a mirror image pin–out of the NTE1898 allowing for easier design of PC boards
when used in BTL–stereo applications.
Features:
D High Power:
POUT = 22W (Typ) @ VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4(BTL)
POUT = 5.8W/Ch (Typ) @ VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4(Dual)
D Low Distortion:
THD = 0.03% (Typ) @ VCC = 14.4V, f = 1kHz, POUT = 4W, RL = 4, GV = 40dB (BTL)
THD = 0.06% (Typ) @ VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4, GV = 52dB (Dual)
D Low Noise:
VNO = 0.14mVrms (Typ) @ VCC = 13.2V, RL = 4, GV = 40dB, Rg = 0, DIN Noise: DIN45405
VNO = 0.7mVrms (Typ) @ VCC = 13.2V, RL = 4, GV = 52dB, BW = 20Hz to 20kHz (Dual)
