General Description
The MAX11129–MAX11132 are 12-/10-bit with external
reference and industry-leading 1.5MHz, full linear band-
width, high speed, low-power, serial output successive
approximation register (SAR) analog-to-digital convert-
ers (ADCs). The MAX11129–MAX11132 include both
internal and external clock modes. These devices feature
scan mode in both internal and external clock modes.
The internal clock mode features internal averaging to
increase SNR. The external clock mode features the
SampleSetK technology, a user-programmable analog
input channel sequencer. The SampleSet approach
provides greater sequencing flexibility for multichannel
applications while alleviating significant microcontroller
or DSP (controlling unit) communication overhead.
The internal clock mode features an integrated FIFO
allowing data to be sampled at high speeds and then held
for readout at any time or at a lower clock rate. Internal
averaging is also supported in this mode improving SNR
for noisy input signals. The devices feature analog input
channels that can be configured to be single-ended
inputs, fully differential pairs, or pseudo-differential inputs
with respect to one common input. The MAX11129–
MAX11132 operate from a 2.35V to 3.6V supply and con-
sume only 15.2mW at 3Msps.
The MAX11129–MAX11132 include AutoShutdownK,
fast wake-up, and a high-speed 3-wire serial interface.
The devices feature full power-down mode for optimal
power management.
The 48MHz, 3-wire serial interface directly connects to
SPI, QSPIK, and MICROWIREM devices without external
logic.
Excellent dynamic performance, low voltage, low power,
ease of use, and small package size make these convert-
ers ideal for portable battery-powered data-acquisition
applications, and for other applications that demand low
power consumption and small space.
The MAX11129–MAX11132 are available in 28-pin, 5mm
x 5mm, TQFN packages and the MAX11131 is available
in a 28-pin TSSOP package. All devices operate over the
-40NC to +125NC temperature range.
