Hello,
I'm looking for a data logger with and ADC capable of >300khz. The aim is to record from an ultrasonic microphone (bat detecting) to a palmtop or laptop.
The requirements are :
USB
12-bit preferably >300khz (bats squeak up to 120khz) battery or PC powered (over USB)There are several solutions in the form of commercial scopes and software, but a homebuild schematic would be great as most of the fancy features of a fast scope aren't needed and cheap ADC don't sample frequently enough.
If someone could point me in the right direction. I'm sure I saw a 8mhz ADC in one of the electronic magazines a while ago but I can't find it now. If someone has some hints I can call up a magazine from the library archive.
Many thanks, Philip
