Description

The MAX1067/MAX1068 low-power, multichannel, 14-bit analog-to-digital converters (ADCs) feature 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. The 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.

The MAX1067/MAX1068 consume only 2.9mA (AVDD =DVDD = +5V) at 200ksps when using an external reference.AutoShutdown. reduces the supply current to 145A at 10ksps and to less than 10A at reduced sampling
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 conversions 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, combined with ease of use and an integrated reference,make the MAX1067/MAX1068 ideal for control and dataacquisition operations or for other applications with demanding power consumption and space requirements. The device is available in a 16-pin QSOP package, and the MAX1068 is available in a 24-pin QSOP package. Both devices are guaranteed over the commercial (0 to +70) and extended (-40 to +85;) temperature ranges. Use the MAX1168 evaluation kit to evaluate the MAX1068.
