14-Bit, 135ksps, Single-Supply ADCs with
Bipolar Analog Input Range
General Description
The MAX1156/MAX1158/MAX1174 14-bit, low-power,
successive-approximation analog-to-digital converters
(ADCs) feature automatic power-down, a factory-
trimmed internal clock, and a byte-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 MAX1156 accepts a 0 to +10V analog input volt-
age range. The MAX1158 accepts a ±10V bipolar ana-
log input voltage range, while the MAX1174 accepts a
±5V bipolar analog input voltage range. All devices
consume no more than 26.5mW at a sampling rate of
135ksps when using an external reference, and 31mW
when using the internal +4.096V reference.
AutoShutdown™ reduces supply current to 0.4mA (typ)
at 10ksps.
The MAX1156/MAX1158/MAX1174 are ideal for high-
performance, battery-powered, data-acquisition appli-
cations. Excellent AC performance (THD = -100dB) and
DC accuracy (±1LSB INL) make the MAX1156/
MAX1158/MAX1174 ideal for industrial process control,
instrumentation, and medical applications.
The MAX1156/MAX1158/MAX1174 are available in a
20-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.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
