MAX11602：2.7V to 3.6V and 4.5V to 5.5V, Low-Power, 4-/8-/12-Channel, 2-Wire Serial 8-Bit ADCs

Lowest Power, Smallest Area, I²C, 4-/8-/12-Channel ADCs with Internal Reference

The MAX11600–MAX11605 low-power, 8-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 and require only 350µA at the maximum sampling rate of 188ksps. AutoShutdown™ powers down the devices between conversions, reducing supply current to less than 1µA at low throughput rates. The MAX11600/MAX11601 provide 4 analog input channels each, the MAX11602/MAX11603 provide 8 analog input channels each while the MAX11604/MAX11605 provide 12 analog input channels. The analog inputs are software configurable for unipolar or bipolar and single-ended or pseudo-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 MAX11601/MAX11603/MAX11605 feature a 2.048V internal reference and the MAX11600/MAX11602/MAX11604 feature a 4.096V internal reference. The MAX11600/MAX11601 are available in 8-pin SOT23 packages. The MAX11602–MAX11605 are available in 16-pin QSOP packages. The MAX11600–MAX11605 are guaranteed over the extended industrial temperature range (-40°C to +85°C). Refer to the MAX11606–MAX11611 for 10-bit devices and to the MAX11612–MAX11617 for 12-bit devices.
