Overview
Ordering number : ENN*7874 LA6570 Overview Features Monolithic Linear IC 5CH Driver (BTL : 4CH, H-Bridge : 1CH) for CD The LA6570 is a 5CH driver (BTL : 4CH, H-bridge : 1CH) for CD players.
• Built-in POWER AMP 5CH (bridge connection (BTL) : 4CH, H-bridge : 1CH) • IO max 1A • Built-in level shift circuit (Except H-bridge.
) • Built-in MUTE circuit (output ON/OFF).
(Operates only for CH1 to CH4 BTL AMP.
No operation for H-bridge and 5VREG.
) • Built-in 5V regulator (with external PNP transistor) • Implements VREF switching function (Select H for external, or L for internal (2.
5 V)) • Built-in overheat protection circuit (Thermal shutdown) Specifications Maximum Ratings at Ta = 25°C Parameter Power supply voltage Allowable operation Maximum output current Maximum input voltage MUTE pin voltage Operating temperature Storage temperature Symbol VCC max Pd max IO max VINB VMUTE Topr Tstg Independent IC Specific board * Each output of CH1 to CH4 and H-bridge Conditions Ratings 14 0.
