Hello Folks,
As an analog guy I get goose pimples when I see converters like the
TLV1508. Impressive performance but, boy, do they need a complicated
liturgy to get data out of them. Many of them must be told via SPI that
I want to read this, that and the other value. Then you must patiently
wait x clock cycles, wasting away bus time. The guy who designs the host
processing will throw his coffee mug at me because there'll be a dozen
of these.
Here is what I am looking for: 10 bits or so, 8 channels, bone-simple
readout, can very very slow, low kHz range. All I need is to read DC
values and it doesn't matter when the exact sampling time was. SPI, I2C,
anything serial works. I mean, with a FIFO in there they should be able
to do continuous autoscan and just dump the last valid set of values
upon request.
Any ideas? I am also looking for 10-12 bit DAC with lots of channels but
that seems to be much simpler.
