MAX11321–MAX11328

1Msps, 10-/12-Bit, 4-/8-/16-Channel ADCs with

Post-Mux External Signal Conditioning Access

General Description

Benefits and Features

The MAX11321–MAX11328 are 12-/10-bit with external

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

low-power, serial-output successive approximation reg-

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

MAX11321–MAX11328 provide external access to the

output of the integrated mux and ADC input, to simplify

conditioning. The MAX11321–MAX11328 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.

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. The

MAX11321–MAX11328 operate from a 2.35V to 3.6V sup-

ply and consume only 5.4mW at 1Msps.
