General Description
The MAX11644/MAX11645 low-power, 12-bit, 1-/2-
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
(MAX11645) or 4.5V to 5.5V (MAX11644) and require
only 6μA at a 1ksps sample rate. AutoShutdown pow-
ers down the devices between conversions, reducing
supply current to less than 1μA at low throughput rates.
The MAX11644/MAX11645 each measure two single-
ended or one differential input. The fully differential ana-
log 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 VDD. The MAX11645 fea-
tures a 2.048V internal reference and the MAX11644
features a 4.096V internal reference.
The MAX11644/MAX11645 are available in an ultra-tiny
1.9mm x 2.2mm WLP package and an 8-pin μMAX
package. The MAX11644/MAX11645 are guaranteed
over the extended temperature range (-40°C to +85°C).
For pin-compatible 10-bit parts, refer to the MAX11646/
MAX11647 data sheet.
