Low-Power, 16-Bit Analog-to-Digital Converters
with Parallel Interface
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.
