Overview
Ordering number : ENN6295 Monolithic Linear IC LA6544M Four-Channel Bridge (BTL) Driver for CD-ROM Overview The LA6544M is a 4-channel bridge (BTL) driver developed for use in CD-ROM systems.
Functions • Bridge connected (BTL) four-channel power amplifier • VCE (residual voltage) minimized (channels 1 to 3) by using two power supplies.
• IOmax: 1.
0 A • Muting circuit provided (output on/off control) Pd max — Ta 2.
