The MAX1167/MAX1168 consume only 2.9mA (AVDD = DVDD = +5V) at 200ksps when using an external reference. AutoShutdownTM reduces the supply current to 145A at 10ksps and to less than 10A at reduced sampling rates. The MAX1167 includes a 4-channel input multiplexer, and the MAX1168 accepts up to eight analog inputs. In addition, digital signal processor (DSP)-initiated conversions are simplified with the DSP frame-sync input and output featured in the MAX1168. The MAX1168 includes a data-bit transfer input to select between 8-bit-wide or 16-bit-wide data-transfer modes. Both devices feature a scan mode that converts each channel sequentially or one channel continuously.
