ICs for Compact Disc/CD-ROM Player AN8497SA 3-channel linear input PWM driver IC s Overview The AN8497SA is a PWM output 3-channel driver IC supporting linear inputs, and best suited for an actuator and a motor drive for CD-ROM and DVD-ROM.

Due to its linear input, a conventional system can be used only by replacing a driver.

And, due to an adoption of PWM output, you can reduce considerably power consumption compared with a conventional driver.

Further a space saving surface mount package is a
