General Description

The MAX11606–MAX11611 low-power, 10-bit, multichan-

nel 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 (MAX11607/

MAX11609/MAX11611) or 4.5V to 5.5V (MAX11606/

MAX11608/MAX11610) 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 conver-

sions, reducing supply current to less than 1µA at low

throughput rates. The MAX11606/MAX11607 have 4 analog

input channels each, the MAX11608/MAX11609 have 8 ana-

log input channels each, while the MAX11610/MAX11611

have 12 analog input channels each. The fully differential

analog inputs are software configurable for unipolar or bipo-

lar, and single ended or differential operation.

The full-scale analog input range is determined by the

internal reference or by an externally applied reference

MAX11609/MAX11611 feature a 2.048V internal reference

and the MAX11606/MAX11608/MAX11610 feature a

4.096V internal reference.

The MAX11606/MAX11607 are available in an 8-pin

able in a 16-pin QSOP package. The MAX11606–

MAX11611 are guaranteed over the extended tempera-

ture range (-40°C to +85°C). For pin-compatible 12-bit

parts, refer to the MAX11612–MAX11617 data sheet. For

pin-compatible 8-bit parts, refer to the MAX11600–

MAX11605 data sheet.
