The MAX1036–MAX1039 low-power, 8-bit, multichannel,
analog-to-digital converters (ADCs) feature internal
track/hold (T/H), voltage reference, clock, and an
I
operate from a single supply and require only 350µA at
the maximum sampling rate of 188ksps. Auto-
Shutdown™ powers down the devices between conver-
sions reducing supply current to less than 1µA at low
throughput rates. The MAX1036/MAX1037 have four ana-
log 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 V
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 guar-
anteed 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.
