The MAX1179/MAX1187/MAX1189 16-bit, low-power,
successive-approximation analog-to-digital converters
(ADCs) feature automatic power-down, a factory-
trimmed internal clock, and a 16-bit wide parallel inter-
face. The devices operate from a single +4.75V to
+5.25V analog supply and feature a separate digital
supply input for direct interface with +2.7V to +5.25V
digital logic.
The MAX1179 accepts a bipolar input voltage range of
±5V. The MAX1187 accepts an analog input voltage
range from 0 to +10V, while the MAX1189 accepts a
bipolar analog input voltage range of ±10V. All devices
consume only 23mW at a sampling rate of 135ksps
when using an external reference and 29mW when
using the internal +4.096V reference. AutoShutdown™
reduces supply current to 0.4mA at 10ksps. The
MAX1179/MAX1187/MAX1189 are ideal for high-perfor-
mance, battery-powered data-acquisition applications.
Excellent AC performance (THD = -100dB) and DC
accuracy (±2LSB INL) make the MAX1179/MAX1187/
MAX1189 ideal for industrial process control, instrumen-
tation, and medical applications.
The MAX1179/MAX1187/MAX1189 are available in a
28-pin TSSOP package and are fully specified over the
-40°C to +85°C extended temperature range and the
0°C to +70°C commercial temperature range.
