Overview
19-2955; Rev 1; 8/07 Multichannel, 14-Bit, 200ksps Analog-to-Digital Converters General Description The MAX1067/MAX1068 low-power, multichannel, 14bit 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 3.
6mA (AVDD = DVDD = +5V) at 200ksps when using an external reference.
AutoShutdown™ reduces the supply current to 185µA at 10ksps and to less than 10µA 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 16bit-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 MAX1067 is available in a 16-pin QSOP package, and the MAX1068 is available in a 24-pin www.

com QSOP package.
Both devices are guaranteed over the commercial (0°C to +70°C) and extended (-40°C to +85°C) temperature ranges.
Use the MAX1168 evaluation kit to evaluate the MAX1068.
