MAX11120–MAX11128

1Msps, Low-Power, Serial 12-/10-/8-Bit,

4-/8-/16-Channel ADCs

General Description

Benefits and Features

S Scan Modes, Internal Averaging, and Internal

The MAX11120–MAX11128 are 12-/10-/8-bit with exter-

nal reference and industry-leading 1.5MHz, full linear

bandwidth, high speed, low-power, serial output suc-

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

converters (ADCs). The MAX11120–MAX11128 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 averag-

ing to increase SNR. The external clock mode features

the SampleSetK technology, a user-programmable ana-

log input channel sequencer. The SampleSet approach

provides greater sequencing flexibility for multichannel

applications while alleviating significant microcontroller

or DSP (controlling unit) communication overhead.

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

S SampleSet: User-Defined Channel Sequence with

Maximum Length of 256

S Analog Multiplexer with True Differential

Track/Hold

 16-/8-/4-Channel Single-Ended

 8-/4-/2-Channel Fully-Differential Pairs

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

a Common Input

S Two Software-Selectable Bipolar Input Ranges

 QV /2, QV

REF+ REF+

S Flexible Input Configuration Across All Channels

S High Accuracy

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 MAX11120–

MAX11128 operate from a 2.35V to 3.6V supply and con-

sume only 5.4mW at 1Msps.

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

Over Temperature Range

S 70dB SINAD Guaranteed at 250kHz Input

Frequency

S 1.5V to 3.6V Wide Range I/O Supply

 Allows the Serial Interface to Connect Directly

to 1.8V, 2.5V, or 3.3V Digital Systems

S 2.35V to 3.6V Supply Voltage

S Longer Battery Life for Portable Applications

 Low Power

The MAX11120–MAX11128 include AutoShutdownK,

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

The devices feature full power-down mode for optimal

power management.

 5.4mW at 1Msps with 3V Supplies

 2µA Full-Shutdown Current

S External Differential Reference (1V to V

)

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

Compatible Serial Interface

The 16MHz, 3-wire serial interface directly connects to

SPI, QSPIK, and MICROWIRE devices without external

S Wide -40NC to +125NC Operation

logic.

S Space-Saving, 28-Pin, 5mm x 5mm TQFN

Packages

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.

S 1Msps Conversion Rate, No Pipeline Delay

S 12-/10-/8-Bit Resolution

Applications

High-Speed Data Acquisition Systems

High-Speed Closed-Loop Systems

Industrial Control Systems

Medical Instrumentation

The MAX11120–MAX11128 are available in 28-pin, 5mm

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

+125NC temperature range.
