1 / 7 page SANYO Electric Co.,Ltd. Semiconductor Company TOKYO OFFICE Tokyo Bldg., 1-10, 1 Chome, Ueno, Taito-ku, TOKYO, 110-8534 JAPAN Ordering number : ENN7901 40804TN (OT) No.7901-1/7 Overview The LA47536 is a 4-channel BTL power amplifier IC developed for use in car audio systems. The output stage 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, RL = 4 Ω) — Po = 28 W (typical) (At VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) • Muting function (pin 22) • Standby switch (pin 4) • Built-in various protection circuits — Output pin-to-VCC short — Output pin-to-GND short — Load short — Over voltage — Thermal shut down • Self-diagnosis function that detects the output offset (pin 25) • Output offset detection on/off switch (pin 1) SANYO Semiconductors DATA SHEET LA47536 Monolithic Linear IC Four-Channel 45 W BTL Car Audio Power Amplifier Any and all SANYO products described or contained herein do not have specifications that can handle applications that require extremely high levels of reliability, such as life-support systems, aircraft's control systems, or other applications whose failure can be reasonably expected to result in serious physical and/or material damage. Consult with your SANYO representative nearest you before using any SANYO products described or contained herein in such applications. SANYO assumes no responsibility for equipment failures that result from using products at values that exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges, or other parameters) listed in products specifications of any and all SANYO products described or contained herein. |
