MAX1067/MAX1068 are low-power, multichannel, 14-bit analog-to-digital converters (ADCs) featuring a successive-approximation ADC, integrated +4.096V reference, a reference buffer, an internal oscillator, automatic power-down, and a high-speed SPI™/QSPI™/MICROWIRE™-compatible interface. MAX1067/MAX1068 operate with a single +5V analog supply and feature a separate digital supply, allowing direct interfacing with +2.7V to +5.5V digital logic. MAX1067/MAX1068 consume only 2.9mA (AVDD = DVDD = +5V) at 200ksps when using an external reference. AutoShutdown™ reduces the supply current to 145µA at 10ksps and to less than 10µA at reduced sam- pling rates. The MAX1067 includes a 4-channel input multiplexer, and the MAX1068 accepts up to eight analog inputs. In addition, digital signal processor (DSP)-initiated con- versions are simplified with the DSP frame-sync input and output featured in the MAX1068. The MAX1068 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. Excellent dynamic performance and low power, com- bined with ease of use and an integrated reference, make the MAX1067/MAX1068 ideal for control and data- acquisition operations or for other applications with demanding power consumption and space require- ments. The MAX1067 is available in a 16-pin QSOP package, and the MAX1068 is available in
