General Description

The MAX1393/MAX1396 micropower, serial-output, 12-

bit, analog-to-digital converters (ADCs) operate with a

single power supply from +1.5V to +3.6V. These ADCs

feature automatic shutdown, fast wake-up, and a high-

speed 3-wire interface. Power consumption is only

of 312.5ksps. AutoShutdown™ between conversions

reduces power consumption at slower throughput rates.

The MAX1393/MAX1396 require an external reference

MAX1393 provides one true-differential analog input

vides two single-ended inputs that accept signals rang-

available through a 5MHz 3-wire SPI™-/QSPI™-/

MICROWIRE™-/digital signal processor (DSP)-compati-

ble serial interface. Excellent dynamic performance,

low voltage, low power, ease of use, and small pack-

age sizes make these converters ideal for portable bat-

tery-powered data-acquisition applications, and for

other applications that demand low power consumption

and minimal space.

The MAX1393/MAX1396 are available in a space-saving

package. The parts operate over the extended (-40°C to

+85°C) and military (-55°C to +125°C) temper-

ature ranges.
