Which (and why?) one do You suggest, with the following specs ?: * 16 input channels * conversion time <= 100 us. * SPI serial interface * low price... :o) TIA, S.- -- http://www.piclist.com hint: PICList Posts must start with ONE topic: "[PIC]:" PIC only "[EE]:" engineering "[OT]:" off topic "[AD]:" ad's
