Looking for device that will output sine wave 1Khz -10Khz

Building a metal detector. need a device that will output a sine wave in the 1Khz -10Khz range that can be amplified to send to the coil.


I’m not aware of any convenient black-box solutions on hand; some assembly will be required.

An internet search for “sine wave oscillator” should turn up a number of resources with the SLOA060 document form TI among them, which contains some good information on useful analog techniques. A more contemporary approach might be the use of a microcontroller in conjunction with a direct digital synthesis device such as an AD9837.
