Motorola 33794 electric field imaging IC



Original poster: "Jim Lux by way of Terry Fritz <teslalist-at-qwest-dot-net>" <jimlux-at-earthlink-dot-net>

Anybody fooled with the MC33794.. it's a thing used to image electric 
fields, typically for air bag controllers, etc.

It "generates a high purity sinewave, steers it to one of 9 external 
electrodes and measures the resutlant field coupled into the non-driven 
electrodes"
