I'm using a new chip I bought the other day. It's the ISD1790. This is supposed to sample at 12kHz and at that rate will provide 60 seconds of recording and playback. (90 seconds at 8kHz)
I'm wondering if anyone has tried this. The datasheet for this chip is really sparse. Not nearly as good as the ISD 2500 series datasheets.
Problem I'm having is that the sound is really really quiet when I play it back through a speaker. The docs suggest I use an 8 ohm speaker. When I do I can barely hear the sound I recorded into the chip.
I'm recording through the analog input where I have a jack connected straight to my computer headphones.
Operationally this seems to be working fine. I would like to be able to use the chip without an amp - but I don't know if I'm going to be able to now.
Has anyone else used this chip? Any ideas?
