1 / 19 page 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 0.734mW (VDD = +1.5V) at the maximum conversion rate of 312.5ksps. AutoShutdown™ between conversions reduces power consumption at slower throughput rates. The MAX1393/MAX1396 require an external reference VREF that has a wide range from 0.6V to VDD. The MAX1393 provides one true-differential analog input that accepts signals ranging from 0 to VREF (unipolar mode) or ±VREF/2 (bipolar mode). The MAX1396 pro- vides two single-ended inputs that accept signals rang- ing from 0 to VREF. Analog conversion results are 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 (3mm x 3mm) 10-pin TDFN package or 10-pin µMAX® package. The parts operate over the extended (-40°C to +85°C) and military (-55°C to +125°C) temper- ature ranges.
