Simple multi-channel serial ADC (8-ch)?

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.
