The MAX1136–MAX1139 low-power, 10-bit, multichannel
analog-to-digital converters (ADCs) feature internal
track/hold (T/H), voltage reference, clock, and an
I
operate from a single supply of 2.7V to 3.6V (MAX1137/
MAX1139) or 4.5V to 5.5V (MAX1136/MAX1138) and
require only 670µA at the maximum sampling rate of
94.4ksps. Supply current falls below 230µA for sampling
rates under 46ksps. AutoShutdown™ powers down the
devices between conversions, reducing supply current to
less than 1µA at low throughput rates. The
MAX1136/MAX1137 have four analog input channels
each, while the MAX1138/MAX1139 have 12 analog input
channels each. The fully differential analog inputs are
software configurable for unipolar or bipolar, and single
ended or differential operation.
The full-scale analog input range is determined by the
internal reference or by an externally applied reference
voltage ranging from 1V to V
MAX1139 feature a 2.048V internal reference and the
MAX1136/MAX1138 feature a 4.096V internal reference.
The MAX1136/MAX1137 are available in an 8-pin µMAX
package. The MAX1138/MAX1139 are available in a
16-pin QSOP package. The MAX1136–MAX1139 are
guaranteed over the extended temperature range
(-40°C to +85°C). For pin-compatible 12-bit parts, refer to
the MAX1236–MAX1239 data sheet. For pin-compatible
8-bit parts, refer to the MAX1036–MAX1039 data sheet.
