Multichannel, 14-Bit, 200ksps Analog-to-Digital

Converters

General Description

The MAX1067/MAX1068 low-power, multichannel, 14-

bit analog-to-digital converters (ADCs) feature a suc-

cessive-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 (AV

= +5V) at 200ksps when using an external refer-

ence. AutoShutdown™ reduces the supply current to

185µA 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 a 24-pin

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 evalua-

tion kit to evaluate the MAX1068.
