LA47536 - Sanyo Semicon Device

LA47536 Four-Channel 45 W BTL Car Audio Power Amplifier

1. Standby Switch Function (pin 4) The pin 4 threshold voltage is set to be 2 VBE. When Vst is 2.0V or higher, the amplifier will be on, and when Vst is 0.7V or lower, the amplifier will be off. Note that pin 4 requires an operating current of at least 40µA. 2. Muting Function The IC is set to the muted state by setting pin 22 to the ground potential. In thi.

Features

a pure complimentary structure that uses V-pnp transistors on the high side and npn transistors on the low side to provide high power and superb audio quality. The LA47536 includes almost all the functions required for car audio use, including a standby switch, a muting function, and each protection circuit. It also provides a self-diagnosis function (output offset detection). Functions and Features
• Voltage gain: 32 dB
• High output power — Pomax(1) = 45 W (typical) (At VCC = 14.4 V, f = 1 kHz, Vi = 2.5 Vrms, RL = 4 Ω) — Pomax(2) = 40 W (typical) (At VCC = 13.7 V, f = 1 kHz, Vi = 2.5 Vrms, .
