HA11539NT

The HA11539NT is designed as one kind of multi-function IC. It provides several peripheral circuits associated with color TV and VCR remote control tuning systems. The functions of this device are:(1)tuner peripheral circuit: 2 input 4 output band switch and pulse amplifier for AFS switch built-in;(2)power supply circuit: +5V power supply for tuner microcomputer and reset pulse output for tuner microcomputer and power supply relay control output;(3)tuner microcomputer peripheral circuit:buffer amolifier for audio control and wave shaper circuit for AC timer.

And features of the HA11539NT are:(1)integrated remote control diode preamp means that n IC shielding is required;(2)volume control characteristics are easilly adjusted using the integrated push-pull output buffer amp;(3)AC power supply wave shapper with hysteresis built-in.

The absolute maximum ratings of the HA11539NT can be summarized as:(1)supply voltage: 15 V or 35 V;(2)power dissipation: 750 mW;(6)operating temperature: -20 to +65 .
