General Description
The MAX1157/MAX1159/MAX1175 14-bit, low-power,
successive-approximation analog-to-digital converters
(ADCs) feature automatic power-down, factory-trimmed
internal clock, and 14-bit wide parallel interface. 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 MAX1157 accepts an analog input voltage range
from 0 to +10V while the MAX1159 accepts a bipolar
analog input voltage range of ±10V. The MAX1175
accepts a bipolar analog input voltage range of ±5V.
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 MAX1157/MAX1159/MAX1175 are ideal for
high-performance, battery-powered data-acquisition
applications. Excellent AC performance (THD = -100dB)
and DC accuracy (±1LSB INL) make the MAX1157/
MAX1159/MAX1175 ideal for industrial process control,
instrumentation, and medical applications.
The MAX1157/MAX1159/MAX1175 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.
