2.7V to 3.6V and 4.5V to 5.5V, Low-Power,  
4-/12-Channel, 2-Wire Serial 10-Bit ADCs  
6–MAX139  
General Description  
Features  
o High-Speed I C-Compatible Serial Interface  
2
The MAX1136–MAX1139 low-power, 10-bit, multichannel  
analog-to-digital converters (ADCs) feature internal  
track/hold (T/H), voltage reference, clock, and an  
400kHz Fast Mode  
1.7MHz High-Speed Mode  
o Single-Supply  
2
I C-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.

o Internal Clock

o 4-Channel Single-Ended or 2-Channel Fully  
Differential (MAX1136/MAX1137)  
o 12-Channel Single-Ended or 6-Channel Fully  
Differential (MAX1138/MAX1139)  
o Internal FIFO with Channel-Scan Mode  
o Low Power  
The full-scale analog input range is determined by the  
internal reference or by an externally applied reference  
voltage ranging from 1V to V . The MAX1137/  
DD  
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.
