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 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 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 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.
