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.
