EVALUATION KIT AVAILABLE

MAX11321–MAX11328

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

Post-Mux External Signal Conditioning Access

General Description

Benefits and Features

S Scan Modes, Internal Averaging, and Internal Clock

S 16-Entry First-In/First-Out (FIFO)

S SampleSet: User-Defined Channel Sequence with

Maximum Length of 256

S Input Pins

Any Combination of Single-Ended, Differential

and Pseudo-Differential Pairs Allowed

S Analog Multiplexer with True Differential

Track/Hold

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.

16-/8-/4-Channel Single-Ended

12-/8-/4-Channel Fully-Differential Pairs

15-/8-/4-Channel Pseudo-Differential Relative to

a Common Input

S Externally Accessible Multiplex Output and

ADC Input

S Two Software-Selectable Bipolar Input Ranges

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.

QV

/2, QV

REF+

S Flexible Input Configuration Across All Channels

S High Accuracy

Q1 LSB INL, Q1 LSB DNL, No Missing Codes

S 70dB SINAD Guaranteed at 100kHz Input

Frequency

S 1.5V to 3.6V Digital I/O Supply Voltage

S 2.35V to 3.6V Supply Voltage

S Extended Battery Life for Portable Applications

5.4mW at 1Msps with 3V Supplies

2µA Full-Shutdown Current

The MAX11321–MAX11328 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

S External Differential Reference (1V to V

)

S 16MHz, 3-Wire SPI-/QSPI-/MICROWIRE-/DSP-

Compatible Serial Interface

S Wide -40NC to +125NC Operation

directly connects to SPI, QSPIK, and MICROWIRE

devices without external logic.

S Space-Saving, 32-Pin, 5mm x 5mm TQFN Packages

S 1Msps Conversion Rate, No Pipeline Delay

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.

Applications

High-Speed Data Acquisition Systems

High-Speed Closed-Loop Systems

Industrial Control Systems

Medical Instrumentation

The MAX11321–MAX11328 are available in 32-pin, 5mm

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

+125NC temperature range.
