ABSTRACT:
A transducer having a regulated power supply for the auxiliary circuits or additional stages using the available power in a transducer module. The voltage required for the regulator is less than lowest transducer circuit output signal as controlled by the output or driver stage. One auxiliary circuit is a self-testing circuit which is responsive to the power-up of the transducer for applying test signals to the transducer for a predetermined time. The tester would include an oscillator for generating test signals in response to a power-up and a disable circuit for disabling the oscillator after the predetermined time as determined by a count of the test signals.
