General Description
The MAX1136–MAX1139 low-power, 10-bit, multichannel
analog-to-digital converters (ADCs) feature internal
track/hold (T/H), voltage reference, clock, and an
I2C-compatible 2-wire serial interface. These devices
operate from a single supply of 2.7V to 3.6V (MAX1137/
MAX1139) or 4.5V to 5.5V (MAX1136/MAX1138) and
require only 670A at the maximum sampling rate of
94.4ksps. Supply current falls below 230A for sampling
rates under 46ksps. AutoShutdown powers down the
devices between conversions, reducing supply current to
less than 1A 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 VDD. The MAX1137/
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 MAX
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.
