MAX11612：Low-Power, 4-/8-/12-Channel, I²C, 12-Bit ADCs in Ultra-Small Packages
Lowest Power, Smallest Area, I²C, 4-/8-/12-Channel ADCs with Internal Reference
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 VDD. 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 and the MAX11613 is available in an ultra-small, 1.9mm x 2.2mm, 12-bump wafer-level package (WLP). The MAX11614–MAX11617 are available in a 16-pin QSOP package and in an ultra-small, 2.14mm x 2.0mm, 16-bump wafer level package (WLP). 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.
