General Description

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.
