NTE1516 Integrated Circuit Audio Power Amp, 1.8 Watt Description: The NTE1516 is a silicon monolithic integrated circuit in an 8−Lead DIP plastic package with a tab designed for audio power amplifiers used in portable radio receivers or portable cassette tape recorders using a 9V power supply. Features: D High Output Power: PO = 2.4W (Typ) at VCC = 9V, RL = 4Ω, T.H.D. = 10% D Wide Operating Voltage Range: VCC = 4.5 to 9 to 11V D High Ripple Rejection Ratio: R.R.R. = 55dB (Typ) D Soft Cripping Waveform. D Contains a Muting Circuit so that No Shock Noise is Heard at Power Supply Switch ON/OFF D Contains a Terminal (Pin2) to Reject Interference Noise in a Strong Electric Field.
