cmoy isnt an output amp
its an opamp =\
a chipamp with an input resistor equal to the speaker the radio expects to see is fine

oh haha
yeah that was last job, like 3 years ago
we ended up renting a schaffner
new job has two
http://www.gruppompb.uk.com/public/upload/NSG-435.jpg
will do up to 8kV contact dischard and 16kV air discharge
esd gun
contact has a steel cone tip, tiny radius, could stab yourself pretty bad
air is just a steel spherical tip, maybe like 1/4" radius
contact you gotta dig through paint and shit
battery doesnt click in well
and it recharges through an 1/8" TS miniplug
the batteries are kinda retarded, thinks its an older model tho

good enough for a lot of stuff
yeah
lots of times the UI (uC) or audio (DSP) will lock up, and the uC watchdog will pull everything out
we self certify, the spec we give to the EMC lab is that our system should always reset without user intervention

why
cheap?
clicking on ti parametric filters, specs look neat
aw damn two watchdog timers
watchdog for your watchdog
was trying to pick which manual
but yeah 13 timers 80mhz excessive spi/i2c
for esd two watchdogs seems ideal
ive done testing on stuff where clearly the watchdog was fucked along with the rest of the uC
