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.

the end of acquisition, the accuracy of the system can
be compromised. To avoid this situation, increase the
acquisition time, use a driving circuit that can settle
within tACQ, or leave the MAX1158/MAX1174 powered
up by setting the voltage at R/C low during the second
falling edge of CS.
Layout, Grounding, and Bypassing
For best performance, use printed circuit boards. Do
not run analog and digital lines parallel to each other,
and do not layout digital signal paths underneath the
ADC package. Use separate analog and digital ground
planes with only one point connecting the two ground
systems (analog and digital) as close to the device as
possible.
Route digital signals far away from sensitive analog and
reference inputs. If digital lines must cross analog lines,
do so at right angles to minimize coupling digital noise
onto the analog lines. If the analog and digital sections
share the same supply, isolate the digital and analog
