2.7V to 3.6V and 4.5V to 5.5V, Low-Power,
4-/8-/12-Channel, 2-Wire Serial, 12-Bit ADCs
General Description
The MAX11612–MAX11617 low-power, 12-bit, multi-
channel 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 of 2.7V to 3.6V
(MAX11613/MAX11615/MAX11617) or 4.5V to 5.5V
(MAX11612/MAX11614/MAX11616) and require only
670µA at the maximum sampling rate of 94.4ksps.
Supply current falls below 230µA for sampling rates
under 46ksps. AutoShutdown™ powers down the
devices between conversions, reducing supply current
to less than 1µA at low throughput rates. The
MAX11612/MAX11613 have 4 analog input channels
each, the MAX11614/MAX11615 have 8 analog input
channels each, while the MAX11616/MAX11617 have
12 analog input channels each. The fully differential
analog inputs are software configurable for unipolar or
bipolar, and single-ended or 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 MAX11613/
MAX11615/MAX11617 feature a 2.048V internal refer-
ence and the MAX11612/MAX11614/MAX11616 feature
a 4.096V internal reference.
The MAX11612/MAX11613 are available in an 8-pin
µMAX^® package. The MAX11614–MAX11617 are avail-
able in a 16-pin QSOP package. The MAX11612–
MAX11617 are guaranteed over the extended tempera-
ture range (-40°C to +85°C). For pin-compatible 10-bit
parts, refer to the MAX11606–MAX11611 data sheet. For
pin-compatible 8-bit parts, refer to the MAX11600–
MAX11605 data sheet.
