They give out free samples on request, and one of their chips (which I happen to have) is a serial, low power, eight channel 12 bit ADC. That chip is the MAX146 (2.7 - 3.6 volts) or the MAX 147 (2.7 - 5.25 volts). They have a whole pile of ADCs, in many configurations (channels/bits). If you only need one or two, it's hard to do better than free! :-) Later, Jon
