The TDA5140A yet embody an Uncommitted Transconductance Amplifier (OTA) that can be appled as a control amplifier. The output is adequate for directly driving an external power transistor. The TDA5140A is built for systems with low current consumption, there are: use of I2L logic, adaptive base drive for the output transistors, likelihood of using a pick-up coil without bias current.

A: Apply momentary ground to reset hours to zero.
B: When using the MTH6 with inductive loads, we recommend installing a suppression diode across all coils.
C: Terminals 4 and 8 may be grounded on negative ground power supply.
D: Alternator must be equipped with a tach terminal (auxiliary AC terminal).
E: Connecting full battery potential to terminal 9 can cause damage
to the switchgage. Shutdown circuit is rated for 300 mA continuous. Circuit grounds out at set point. [...]

Integrated laser drivers is recommended for fast switching, since signal changes will move faster because of reduced wiring line inductance and capacitance. The use of integrated laser driver circuit gives some benefit such as: output power stability improvement, board space reduction, error monitoring, better dynamic performance, and MTBF reliability improvement. [...]

The phase shift oscillator works in such a way that if the amplitude of the inverting amplifier is not high enough the system will continually attenuate the signal until the amplitude is zero, it was therefore decided to change the amplification power of the inverting amplifier. [...]
