The MAX11329–MAX11332 are 12-/10-bit with external

reference and 500kHz, full-linear-bandwidth, high-speed,

low-power,

ister (SAR) analog-to-digital converters (ADCs). The

MAX11329–MAX11332 provide external access to the

output of the integrated mux and ADC input, to simplify the

signal conditional circuitry. The MAX11329–MAX11332

include both internal and external clock modes.

devices feature scan mode in both internal and external

clock modes. The internal clock mode features internal

averaging

tures the 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.

External pins provide access to the output of the

multiplexer and ADC inputs to simplify multichannel sig-

nal conditioning. The internal clock mode features an inte-

grated 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 internal clock

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.

ply and consume only 15.2mW at 3Msps.

The MAX11329–MAX11332 include

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

The devices feature full power-down mode for optimal

power management.

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 MAX11329–MAX11332 are available in 32-pin, 5mm

x 5mm, TQFN packages and operate over the -40NC to

+125NC temperature range.
