NTE7145
Intergrated Circuit
18W BTL x 2 Ch Audio Power Amplifier
Description:
The NTE7145 is a stereo audio power IC in a 17–Lead Staggered SIP type package designed for car
audio use. This device has 2 built–in channels to reduce the characteristics difference between L and
R channels. In addition, the functions of stand–by, muting, and a variety of protections circuits are
involved.
Features:
D High Power:
P_OUT(1) = 18W (Typ)/Channel (V_CC = 14.4V, f = 1kHz, THD = 10%, R_L = 4Ω)
P_OUT(2) = 15W (Typ)/Channel (V_CC = 13.2V, f = 1kHz, THD = 10%, R_L = 4Ω)
D Low Distortion Ratio:
THD = 0.04% (Typ) (V_CC = 13.2V, f = 1kHz, P_OUT = 1W, R_L = 4Ω, G_V = 50dB)
D Low Noise:
V_NO = 0.30mV_rms (Typ) (V_CC = 13.2V, R_L = 4Ω, G_V = 50dB, R_g = 0Ω, BW = 20Hz to 20kHz)
D Built–In Stand–By Function (With Pin4 set at Low, Power is Turned OFF):
I_SB = 1µA (Typ)
D Built–In Muting Function (With Pin1 set at Low, Power is Turned OFF):
V (Mute) = 1V (Typ)
D Built–In Various Protection Circuits:
Thermal Shut Down
Overvoltage
OUT→V_CC Short
OUT→GND Short
OUT–OUT Short
D Operating Supply Voltage: V_CC = 9V to 18V
Absolute Maximum Ratings: (T_A = +25°C unless otherwise specified)
