The MAX11129–MAX11132 are 12-/10-bit with external

reference and industry-leading 1.5MHz, full linear band-

width, high speed,

approximation register (SAR) analog-to-digital convert-

ers (ADCs). The MAX11129–MAX11132 include both

internal and external clock modes.

scan mode in both internal and external clock modes.

The internal clock mode features internal averaging

SampleSetK technology, a user-programmable analog

input channel sequencer.

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.

sume only 15.2mW at 3Msps.

The MAX11129–MAX11132 include

fast wake-up, and a high-speed 3-wire serial interface.

The devices feature full power-down mode for optimal

power management.

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 operate over the -40NC to

+125NC temperature range.
