• Description

   

  The DRV134 and DRV135 are differential output amplifiers that convert a single-ended input to a balanced output pair. These balanced audio drivers consist of high performance op amps with on-chip precision resistors. They are fully specified for high performance audio applications and have excellent ac specifications, including low distortion (0.0005% at 1 kHz) and high slew rate (15 V/µs).

  The on-chip resistors are laser-trimmed for accurate gain and optimum output common-mode rejection. Wide output voltage swing and high output drive capability allow use in a wide variety of demanding applications. They easily drive the large capacitive loads associated with long audio cables. Used in combination with the INA134 or INA137 differential receivers, they offer a complete solution for transmitting analog audio signals without degradation.

  The DRV134 is available in 8-pin DIP and SOL-16 surface-mount packages. The DRV135 comes in a space-saving SO-8 surface-mount package. Both are specified for operation over the extended industrial temperature range, –40°C to +85°C and operate from –55°C to +125°C

Description

BD7907FS is a 6-channel driver IC that integrates all
drivers necessary for CD-ROM, and DVD-ROM systems
into a single chip.  The built-in 2-channel sled motor
driver is used for the stepping motor.  Low heat operation
can be achieved by applying the PWM driving system for
sled and spindle motor drivers.

 Features

1) Motor drivers for spindle, sled (2-channel) and
loading, and actuator drivers for tracking are all
integrated into a single chip.
2) ON/OFF for each driver, brake mode switching of
spindle and stand-by mode switching can be
controlled by 2-wire serial data.  
3) Built-in triangular-wave generator
4) SSOP-A54 package
5) Built-in thermal shut-down circuit

6) Highly efficient by applying the PWM drive and
Low ON resistance POWER MOSFET
7) Built-in current limit, hall bias, short brake, FG 3-phase
synthesis output, and reverse protection circuit

8) Highly efficient due to the PWM drive
9) Built-in 2-channel for the stepping motor

10) Low noise due to the linear BTL driver and smooth spin

 Applications

CD-ROM, DVD-ROM, and any other equipment driven by optical DISC
