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 (AVDD =
DVDD = +5V) at 200ksps when using an external refer-
ence. AutoShutdown reduces the supply current to
185A at 10ksps and to less than 10A 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.
