General Description
The MAX1392/MAX1395 micropower, serial-output,
10-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
0.740mW (V
DD
= +1.5V) at the maximum conversion
rate of 357ksps. AutoShutdown between conversions
reduces power consumption at slower throughput rates.
The MAX1392/MAX1395 require an external reference
V
REF
that has a wide range from 0.6V to V
DD
. The
MAX1392 provides one true-differential analog input
that accepts signals ranging from 0 to V
REF
(unipolar
mode) or ±V
REF
/2 (bipolar mode). The MAX1395 pro-
vides two single-ended inputs that accept signals rang-
ing from 0 to V
REF
. Analog conversion results are
available through a 5MHz, 3-wire SPI-/QSPI-
/MICROWIRE-/digital signal processor (DSP)-compat-
ible 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 MAX1392/MAX1395 are available in a space-sav-
ing (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) tem-
perature ranges.
