The MAX1036MAX1039 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 350A at the maximum sampling rate of 188ksps. AutoShutdownTM powers down the devices between conversions reducing supply current to less than 1A 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 singleended 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 V DD . 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 16pin QSOP packages. The MAX1036MAX1039 are guaranteed over the extended industrial temperature range (-40C to +85C). Refer to MAX1136MAX1139 for 10-bit devices and to the MAX1236MAX1239 for 12-bit devices.
