Integrated Circuit
Dual Audio Preamp w/ ALC
Description:
The NTE1517 is an integrated circuit consisting of a dual preamplifier with ALC. It is designed for use
in stereo equipment or radio−cassette recorders. The device consists of two independent high−gain,
low−distortion amplifiers and ALC on a single chip. By using an external switch, the NTE1517 can be
used as a stereo preamplifier with good channel balance.
Features:
D Low Noise: VNI = 1μVrms (Rg = 620Ω, BW = 20Hz to 20kHz)
D High Gain: GVO = 80dB typ.
D Low Distortion: THD = 0.1% typ. (GVC = 46dB, VO = 0.3Vrms)
D Low Supply Current: 6mA typ.
D Built−in Circuit to Reduce Shock−Noise at Switch−On
D Does not require an Input Coupling Capacitor
Absolute Maximum Ratings: (TA = +25°C unless otherwise specified)
