General Description
The MAX11606–MAX11611 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.

6V (MAX11607/ MAX11609/MAX11611) or 4.
5V to 5.
5V (MAX11606/ MAX11608/MAX11610) 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 MAX11606/MAX11607 have 4 analog input channels each, the MAX11608/MAX11609 have 8 analog input channels each, while the MAX11610/MAX11611 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 DD .
The MAX11607/ MAX11609/MAX11611 feature a 2.
048V internal reference and the MAX11606/MAX11608/MAX11610 feature a 4.
096V internal reference.
The MAX11606/MAX11607 are available in an 8-pin µMAX® package.
The MAX11608–MAX11611 are available in a 16-pin QSOP package.
The MAX11606– MAX11611 are guaranteed over the extended temperature range (-40°C to +85°C).
For pin-compatible 12-bit parts, refer to the MAX11612–MAX11617 data sheet.
For pin-compatible 8-bit parts, refer to the MAX11600– MAX11605 data sheet.
