A while back, I designed a product around a MAX1409, but they are now very difficult to find, and the client wants me to redesign the product to use a part he can get. The MAX1409 was an ideal part for the product, assuming we could get it. It as a 16 bit sigma delta (or is that delta sigma?) ADC, internal reference (though our sensor is ratiometric, so the reference stability is not critical), 10 bit DAC, and real time clock, all on an SPI interface. Anyone have ideas of a replacement device? THANKS!
