It has a low input impedance which loads down the signal level from the high output impedance of a piezo mic and the transistor has low voltage gain so if ratasheet speak loudly you will make an output.

Posted August 11, No license, express, implied or otherwise, is granted hereby under any patents, copyrights or other intellectual property rights of Renesas Electronics or others.

The circuit you found will not work with a Jfet but will work with an NPN transistor and a low impedance signal source not a piezo. The preamp works with the 3. If an N-channel Jfet is used then its gate must have a 2. The recommended applications of an NEC Electronics product depend on its quality grade, as indicated below.

You should use the Renesas Electronics products described in this document within the range specified by Renesas Electronics, especially with respect to the maximum rating, operating supply voltage range, movement power voltage range, heat radiation characteristics, 2cs1623 and other product characteristics.

Silicon Epitaxial Planar Transistor

Renesas Electronics products are classified according to the following three quality grades: In the attachment I prepared a schematic of the preamp. Please use Renesas Electronics products in compliance with all applicable laws and regulations that regulate the inclusion or use of controlled substances, including without limitation, the EU RoHS Directive.

Posted January 3, The information is subject to change without notice. Register a new account. Before purchasing or using any Renesas Electronics products listed herein, please confirm the latest product information with a Renesas Electronics sales office.


I just copied it from the PCB that was in the throat-mic housing. Further, you may not use any Renesas Electronics product for any application for which it is not intended without the prior written consent of Renesas Electronics. Aircraft; aerospace equipment; submersible repeaters; nuclear reactor control systems; medical equipment or systems for life support e. You must check the quality grade of each Renesas Electronics product before using it in a particular application.

Also, please pay regular and careful attention to additional and different information to be disclosed by Renesas Electronics such as that disclosed through our website. Descriptions of circuits, software and other related information in this document are provided only to illustrate the operation of semiconductor products and application examples. NEC Electronics assumes no responsibility for any errors that may appear in this document. The sound card needs to form part of the circuit.

Renesas Electronics has used reasonable care in preparing the information included in this document, but Renesas Electronics does not warrant that such information is error free. The pickup is a simple piezo-disc buzzer used in a very cheap throat microphone.
