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 3.6mA (AV
DD
=
DV
DD
= +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 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.
