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 high-
speed 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
VREF that has a wide range from 0.6V to VDD. 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 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, as well as
other applications that demand low-power consumption
and minimal space.
The MAX1391/MAX1394 are available in a space-sav-
ing (3mm x 3mm), 10-pin TDFN package. The parts
operate over the extended (-40°C to +85°C) tempera-
ture range.
