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.
