The MAX1065/MAX1066 14-bit, low-power successive
approximation analog-to-digital converters (ADCs) fea-
ture automatic power-down, a factory-trimmed internal
clock, and a high-speed, 14-bit-wide (MAX1065) or
byte-wide (MAX1066) parallel interface. The devices
operate from a single 4.75V to 5.25V analog supply and
a 2.7V to 5.25V digital supply.
The MAX1065/MAX1066 use an internal 4.096V refer-
ence or an external reference. The MAX1065/MAX1066
consume only 1.8mA at a sampling rate of 165ksps with
external reference and 2.7mA with internal reference.
AutoShutdown™ reduces supply current to 0.1mA at
10ksps.
The MAX1065/MAX1066 are ideal for high-performance,
battery-powered, data-acquisition applications.
Excellent dynamic performance and low-power con-
sumption in a small package make the MAX1065/
MAX1066 the best choice for circuits with demanding
power consumption and space requirements.
The 14-bit-wide MAX1065 is available in a 28-pin TSSOP
package, and the byte-wide MAX1066 is available in a
20-pin TSSOP package. Both devices are available in
either the 0°C to +70°C commercial, or the -40°C to
+85°C extended temperature range.
