SPSC2 Does anybody make a micro with 3 DACs MooseFET wrote: I have an application where I need 3 DACs controlled by a micro. Right now I have a quad DAC chip external to the processor. If a small processor had 3 or more DACs, it could save me a bit of space and signal connections. 16 bitters preferred but 12 bit may work. I can't... 24 Apr 2010 11:39
GR1862-B help, please ...not a happy camper re my GR. Those two 100Meg resistors inside were rather high; one about 9% high and the other about 4% high - a good reason why the 100Gohm 1% resistor i bought (as a reference) read around 5% high on the GR. So..i bought two SlimMox 100Meg 1% 5KV rating resistors for replacement; th... 27 Apr 2010 05:25
Built-in audio playback module Apparently these low power Chinese Z80 microprocessors work as subsystems. The Chinese build them into.. $10 MP3 players, JPEG electronic photo picture frames, Movie players, CAMERAS, Talking kids toys, etc. etc.. Bottom end versions run cool at 24 MHz with a top end of 60 MHz and do USB, LCD, MP/3 whi... 23 Apr 2010 21:25
Optocoupler question.... Hi all, I have a need to detect when an ac voltage has dropped. I thought I'd use an opto coupler (4n25 or 4n37 etc) as the isolation part. The problem I have is that I need an output that will supply power when the led part of the isolator is dark. Currently I have breadboarded a simple cicuit using one... 23 Apr 2010 21:24
HS gate drive transformer? I wound a toroid to use as a HS gate drive transformer for a 100W two switch flyback. I'm using the typical DC restore technique AC couple the transformer. Here's my schematic; http://i42.tinypic.com/9gvyow.png I'm using a PIC and a FET driver to simulate the extremes of the PWM controller duty cycle an... 28 Apr 2010 21:59

If a small processor had 3 or more DACs, it could save me a bit of space and signal connections. 16 bitters preferred but 12 bit may work.

HV diodes Anyone know of a s/mount alternative for HV03-10 ? The circuit has 2 in series+ 2 in parallel. I could use more in series to get to 10KV rating/400mA TIA ... 30 Apr 2010 00:46 |
