This IC is a 4-ch BTL driver developed for driving CD player motors and actuators.
With built-in 3.3V (MM1469PH) or 5.0V (MM1469XH) regulator and general-purpose op amp, it supports a
variety of applications.
(1) External resistor allows gain adjustment.
(2) Few external parts.
(3) Built-in 3.3V or 5.0V regulator. (Requires external PNP Tr.)
(4) Built-in general-purpose op amp.
(5) Built-in thermal shutdown circuit.
HSOP-28
(1) CD radio cassette recorder
(2) VCD
note Constane in parenehesis is regulator output voltage 3.3V(MM1469PH).
