MAX11612EUA+

P1-P3P4-P6P7-P9P10-P12P13-P15P16-P18P19-P21P22-P24
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
I
2
C-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 and the MAX11613 is available in an
ultra-small, 1.9mm x 2.2mm, 12-bump wafer-level pack-
age (WLP). The MAX11614–MAX11617 are available in a
16-pin QSOP package and in an ultra-small, 2.14mm x
2.0mm, 16-bump wafer level package (WLP). The
MAX11612–MAX11617 are guaranteed over the extend-
ed temperature range (-40°C to +85°C). For pin-compati-
ble 10-bit parts, refer to the MAX11606–MAX11611 data
sheet. For pin-compatible 8-bit parts, refer to the
MAX11600–MAX11605 data sheet.
