AN7194K, AN7194Z Dual BTL 50 W single power supply class-H power amplifier IC n Overview The AN7194K and AN7194Z are single power sup- ply, BTL, audio class-H power amplifier ICs. A class-H power amplifier can be made up when this ICs are used in combination with the AN7077Z which is separately mar- ket-available, and it is possible to make a low consump- tion power system. Also, the AN7194K and AN7194Z are incorporating various protection circuits, so that those ICs contribute to the high reliability design of set. n Features

  • Incorporating various protection circuits : Thermal protection, load short-cirucit, short circuit to V CC and short circuit to GND, overvoltage.
  • Built-in stand-by function (Free from shock noise when standby turns-on/off)
  • Built-in muting function Free from shock noise at mute-on/off Adapting attenuator method so that abnormal sound is not generated due to waveform deformation Attack time, recovery time are 20 ms or less
  • Reduction in external components NF and BS electrolytic capacitors are needless RF electrolytic capacitor is needless External muting function is needless
  • OR output terminal is provided
  • Designed for headphone use
  • The AN7194K is of a 16-pin and the AN7194Z is of a 15-pin package n Applications
  • Miniature audio component, CD player radio cassette, karaoke are other audio equipment HZIP016-P-0665B 11.3±0.3 7.7±0.3 (10.0) 29.6±0.3 (10.0) 20.0±0.3 28.0±0.3 29.75±0.3 (0.6) 0.6(0.889) (1.1) (0.889) 161 +0.15 -0.10 f3.6 R1.8 3.5±0.2 1.788 1.45±0.151.80±0.15 (2.54) 1.2+0.1 0.25+0.10 -0.05 (12.5) (14.1) (18.7) (1.2) (21.5) (17.63) R0.7 AN7194K HZIP015-P-0745A AN7194Z 18.00±0.30 13.50±0.30 f3.60±0.10 10.0±0.30 11 5 4.00±0.20 1.50±0.10 0.50 +0.20 –0.10 (0.61) (2.54) 0.25 +0.15 –0.05 R0.553.25±0.10 13.25±0.30 18.95±0.50 15.65±0.50 1.27 (1.80)(1.95) 19.00±0.30 19.30±0.30 2.40±0.50

Always attach an outside heat sink when using the chip. In addition, the outside heat sink must be fastened onto a chassis for use. 2. Connect the cooling fin to GND potential. 3. Avoid short circuit to VCC and short circuit to GND, and load short-circuit. 4. The temperature protection circuit will be actuated at Tj = approx. 150°C. However, it is automatically reset when the chip temperature drops below the above set level. 5. The overvoltage protection circuit starts its operation at VCC = approx. 26 V. 6. For the standby voltage, a stabilized power supply of 3 V or higher should be used. 7. Only when being used in combination with the AN7077Z, this IC can operate up to the supply voltage of approx. 25.4 V which is the maximum output voltage of the AN7077Z.
