The MAX11600–MAX11605 low-power, 8-bit, multichan-
nel, 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 MAX11600/MAX11601 provide 4
analog input channels each, the MAX11602/MAX11603
provide 8 analog input channels each while the
MAX11604/MAX11605 provide 12 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
MAX11603/MAX11605 feature a 2.048V internal refer-
ence and the MAX11600/MAX11602/MAX11604 feature
a 4.096V internal reference.
The MAX11600/MAX11601 are available in 8-pin SOT23
packages. The MAX11602–MAX11605 are available in
16-pin QSOP packages. The MAX11600–MAX11605 are
guaranteed over the extended industrial temperature
range (-40°C to +85°C). Refer to the MAX11606–
MAX11611 for 10-bit devices and to the MAX11612–
MAX11617 for 12-bit devices.
19-4554; Rev 2; 3/10
