Optical disc ICs
4-channel BTL driver for CD
BA6998FP
BA6998FP
The BA6998FP ICs contain a 4-channel BTL driver, 5V regulator (which requires an externally connected PNP transistor),
multi-purpose operational amplifier, and reset output for use with CD players. Also equipped with an input pin for gain
adjustment for all channels of the driver block so that the gain can be adjusted to the desired value for your application.
Furthermore, a built-in level shift circuit exists to further reduce the amount of external components required.
zFeatures
1) 4ch Driver for BTL.
2) Small surface mounting power package (HSOP 28pin).
3) Adjustable gain by the external resistors.
4) Incorporates a thermal shut down circuit.
5) Incorporates a voltage regulator (5V) (PNP Tr is needed outside).
6) Incorporates an operational amplifier.
7) Incorporates a reset-output terminal.

D1695

This part is a darlington connection NPN silicon epitaxial transistor. The 2SD1695 is a Darlington connection transistor and incorporates a dumper diode between the collector and emitter and a constant voltage diode and protection elements between the collector and base. This transistor is ideal for drives in solenoid and actuators.
