Maxim Integrated MAX1391

The MAX1391 provides one true-differential analog input that accepts signals ranging from 0 to VREF (unipolar mode) or ±VREF/2 (bipolar mode). The MAX1394 provides two single-ended inputs that accept signals ranging from 0 to V REF . The MAX1391/MAX1394 are available in a space-saving (3mm x 3mm), 10-pin TDFN package.

GENERAL DESCRIPTION

The MAX1391/MAX1394 micropower, serial-output, 8-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 highspeed 3-wire interface. Power consumption is only 0.743mW (VDD = +1.5V) at the maximum conversion rate of 416ksps. AutoShutdown™ between conversions reduces power consumption at slower throughput rates. The MAX1391/MAX1394 require an external reference V REF that has a wide range from 0.6V to V DD . Analog conversion results are available through a 5MHz 3-wire SPI™-/QSPI™-/ MICROWIRE™-/digital signal processor (DSP)-compatible serial interface. Excellent dynamic performance, low voltage, low power, ease of use, and small package sizes make these converters ideal for portable battery-powered data-acquisition applications, as well as other applications that demand low-power consumption and minimal space. The parts operate over the extended (-40°C to +85°C) and military (-55°C to +125°C) temperature ranges.
