The MAX1036–MAX1039 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 MAX1036/MAX1037 have four analog input channels each, while the MAX1038/MAX1039 have twelve 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 MAX1037/MAX1039 feature a 2.048V internal reference and the MAX1036/MAX1038 feature a 4.096V internal reference. The MAX1036/MAX1037 are available in 8-pin SOT23 packages. The MAX1038/MAX1039 are available in 16-pin QSOP packages. The MAX1036–MAX1039 are guaranteed over the extended industrial temperature range (-40°C to +85°C). Refer to MAX1136–MAX1139 for 10-bit devices and to the MAX1236–MAX1239 for 12-bit devices.
