The MAX11612–MAX11617 low-power, 12-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 (MAX11613/MAX11615/MAX11617) or 4.5V to 5.5V (MAX11612/MAX11614/MAX11616) 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 MAX11612/MAX11613 have 4 analog input channels each, the MAX11614/MAX11615 have 8 analog input channels each, while the MAX11616/MAX11617 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 MAX11613/MAX11615/MAX11617 feature a 2.048V internal reference and the MAX11612/MAX11614/MAX11616 feature a 4.096V internal reference.

The MAX11612/MAX11613 are available in an 8-pin μMAX? package. The MAX11614–MAX11617 are available in a 16-pin QSOP package. The MAX11612–MAX11617 are guaranteed over the extended temperature range (-40°C to +85°C). For pin-compatible 10-bit parts, refer to the MAX11606–MAX11611 data sheet. For pin-compatible 8-bit parts, refer to the MAX11600–MAX11605 data sheet.
