MAX11190

4-Channel, Dual, Simultaneous Sampling,

2.2V to 3.6V, 12-Bit, 3Msps SAR ADC in Tiny

3mm x 3mm TQFN Package

General Description

Beneﬁts and Features

●ꢀ IntegrationꢀandꢀPackagingꢀSaveꢀSpaceꢀ

The MAX11190 is a 4-channel, dual, multiplexed, 12-bit,

compact, high-speed, low-power, successive approxi-

mation analog-to-digital converter (ADC). This high-

performance dual ADC includes high-dynamic range

sample-and-holds and a high-speed serial interface. This

ADC accepts a full-scale input from 0V to the reference

voltage.

• Simultaneous Sampling

• Dual, 4-Channel, Single-Ended 12-Bit Resolution

ADC (2 x 2)

• 16-Pin, 3mm x 3mm TQFN Package

●ꢀ ExcellentꢀPerformanceꢀIdealꢀforꢀMotorꢀControlꢀ

Applications

The device features two dual, single-ended analog inputs

connected to two ADC cores using 2:1 MUXs. The device

also includes a separate supply input for data interface

and dedicated inputs for reference voltage.

• 72dB SNR

• 3Msps Conversion Rate without Pipeline Delay

• External Reference Inputs

• Wide -40°C to +125°C Operation

This device operates from a 2.2V to 3.6V supply and

consumes only 10.5mW at 3Msps. The device includes

full power-down mode and fast wake-up for optimal

power management and a high-speed 3-wire serial inter-

face. The 3-wire serial interface directly connects to SPI,

Requirements

•ꢀ VeryꢀLowꢀPowerꢀConsumptionꢀatꢀ5μA/ksps

• 10.5mW at 3Msps

• 2.2V to 3.6V Supply Voltage

•ꢀ 2.6μAꢀPower-DownꢀCurrentꢀ

QSPI™, and MICROWIRE devices without external

logic. Each of the two internal ADCs has its own dedicated

DOUTA/DOUTB for faster data communication.

●ꢀ DualꢀSPIꢀPortsꢀSimplifiesꢀSystemꢀDesign

• SPI-/QSPI-/MICROWIRE-Compatible Serial

Interface with Two DOUTA/DOUTB Pins

• Dedicated Digital Output Supply Allows Serial

Interface to Directly Connect to 1.5V, 1.8V, 2.5V, or

3V Digital Systems

Excellent dynamic performance, low voltage, low power,

ease of use, and small package size make this converter

ideal for simultaneous data-acquisition applications, and

for other applications that demand low power consump-

tion and minimal space.
