General Description

The MAX1165/MAX1166 16-bit, low-power, successive-

approximation analog-to-digital converters (ADCs) fea-

ture automatic power-down, factory-trimmed internal

clock, and a 16-bit wide (MAX1165) or byte wide

(MAX1166) 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 MAX1165/MAX1166 use an internal 4.096V refer-

ence or an external reference. The MAX1165/MAX1166

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 MAX1165/MAX1166 are ideal for high-perfor-

mance, battery-powered, data-acquisition applications.

Excellent dynamic performance and low power con-

sumption in a small package make the MAX1165/

MAX1166 ideal for circuits with demanding power con-

sumption and space requirements.

The 16-bit wide MAX1165 is available in a 28-pin

TSSOP package and the byte wide MAX1166 is avail-

able 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.
