Maxim Integrated
Detailed Description
The MAX1032/MAX1033 multirange, low-power, 14-bit
successive-approximation ADCs operate from a single
+5V supply and have a separate digital supply allowing
digital interface with 2.7V to 5.25V systems. These 14-bit
ADCs have internal track-and-hold (T/H) circuitry that
supports single-ended and fully differential inputs. For
single-ended conversions, the valid analog input voltage
range spans from -3 x VREF below ground to +3 x VREF
above ground. The maximum allowable differential input
voltage spans from -6 x VREF to +6 x VREF. Data can be
converted in a variety of software-programmable chan-
nel and data-acquisition configurations. Microprocessor
(μP) control is made easy through an SPI-/QSPI-/
MICROWIRE-compatible serial interface.
The MAX1032 has eight single-ended analog input
channels or four differential channels (see the
Block
Diagram at the end of the data sheet). The MAX1033 has
four single-ended analog input channels or two differential
channels. Each analog input channel is independently soft-
ware programmable for seven single-ended input ranges
(0 to (3 x VREF)/2, (-3 x VREF)/2 to 0, 0 to 3 x VREF, -3 x
VREF to 0, (±3 x VREF)/4, (±3 x VREF)/2, ±3 x VREF) and
three differential input ranges (±3 x VREF)/2, ±3 x VREF, ±6
x VREF. Additionally, all analog input channels are fault tol-
erant to ±16.5V. A fault condition on an idle channel does
not affect the conversion result of other channels.
