General Description
The MAX1377/MAX1379/MAX1383 feature two simulta-
neous-sampling, low-power, 12-bit ADCs with serial
interface and internal voltage reference. Fast sampling
rate, low power dissipation, and excellent dynamic per-
formance make the MAX1377/MAX1379/MAX1383
ideal for industrial process control, motor control, and
RF applications.
Conversion results are available through a SPI-/
QSPI-/MICROWIRE-/DSP-compatible interface with
independent serial digital outputs for each channel. The
serial outputs allow twice as much data to be transferred
at the given clock rate. The conversion results for both
ADCs can also be output on a single digital output for
microcontrollers (Cs) and DSPs with only a single serial
input available.
The MAX1377 operates from a 2.7V to 3.6V analog sup-
ply and the MAX1379/MAX1383 operate from a 4.75V
to 5.25V analog supply. A separate 1.8V to AVDD digi-
tal supply allows interfacing to low voltage logic without
the use of level translators.
Two power-down modes, partial and full, allow the
MAX1377/MAX1379 and MAX1383 (full power-down only)
to save power between conversions. Partial power-down
mode reduces the supply current to 2mA while leaving
the reference enabled for quick power-up. Full power-
down mode reduces the supply current to 1A.
The MAX1377/MAX1379 inputs accept voltages
between zero and the reference voltage or ±VREF/2.
The MAX1383 offers an input voltage range of ±10V,
which is ideal for industrial and motor-control applica-
tions. The input to each of the ADCs supports either a
true-differential input or two single-ended inputs.
The MAX1377/MAX1379/MAX1383 are available in a
20-pin TQFN package, and are specified for the automo-
tive (-40°C to +125°C) temperature range.
