General Description

The MAX1167/MAX1168 low-power, multichannel, 16-

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

MAX1167/MAX1168 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 MAX1167/MAX1168 consume only 2.9mA (AV

= +5V) at 200ksps when using an external reference.

AutoShutdown™ reduces the supply current to 145µA at

10ksps and to less than 10µA 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 con-

versions 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.

Excellent dynamic performance and low power, com-

bined with ease of use and an integrated reference, make

the MAX1167/MAX1168 ideal for control and data-acqui-

sition operations or for other applications with demanding

power consumption and space requirements. The

MAX1167 is available in a 16-pin QSOP package and the

MAX1168 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 evaluation kit to evaluate the

MAX1168.
