General Description

The MAX1036–MAX1039 low-power, 8-bit, multichannel,

analog-to-digital converters (ADCs) feature internal

track/hold (T/H), voltage reference, clock, and an

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

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.
