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

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

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

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.
