AN7511, AN7511S 1-W BTL audio power amplifier I Overview The AN7511 and AN7511S are the audio power am- plifier ICs with 1-ch output. The BTL (Balanced Trans- former-Less) method can provide fewer external parts and more easy design for applications. I Features

  • 1-W output (8 Ω) with supply voltage of 5 V: AN7511
  • 0.5-W output (16 Ω) with supply voltage of 5 V: AN7511S
  • On-chip standby function
  • On-chip muting function I Applications
  • Televisions, radios, and personal computers I Block Diagram Attenuator Ripple rejection circuit Thermal shutdown Attenuator control VCC Standby GND (for output) Output Output GND Mute Input 28 dB 28 dB DIP008-P-0300 SOP008-P-0225C Unit: mm Unit: mm AN7511S AN7511 6.4±0.2 7.62±0.303° to 15° 0.30 +0.10 –0.05 0.30±0.26 2.540.5 0.9 1.01.3 1.5 9.2±0.2 0.50±0.20 0° to10° 0.15±0.10 (1.05) 5.01±0.20 4.30±0.20 6.40±0.20 Seating plane 1.75max. 1.45±0.10 0.40+0.10 –0.05 0.10 1.27(0.60)

  • Please avoid the short circuit to VCC , ground, or load short circuit.
  • Please connect the cooling fin with the GND potential.
  • The thermal shutdown circuit operates at about Tj = 150°C. However, the thermal shutdown circuit is reset automati- cally if the temperature drops.
  • Please carefully design the heat radiation especially when you take out high power at high VCC .
  • Please connect only the ground of signal with the signal GND of the amplifier in the previous stage.
