MAX11108
EVALUATION KIT AVAILABLE
Tiny, 2.1mm x 1.6mm, 3Msps,
Low-Power, Serial 12-Bit ADC
General Description
The_  MAX11108 is a tiny (2.1mm x 1.6mm), 12-bit, com-
pact, high-speed, low-power, successive approximation
analog-to-digital converter (ADC). This high-performance
ADC includes a high-dynamic range sample-and-hold
and a high-speed serial interface. This ADC accepts a
full-scale input from 0V to the power supply or to the ref-
erence voltage.
The MAX11108 features a single-ended analog input
connected to the ADC core. The device also includes a
separate supply input for data interface and a dedicated
input for reference voltage.
The MAX11108 "communicates" from 1.5V to V_DD and
operates from a 2.2V to 3.6V supply. The device con-
sumes only 6.6mW at 3Msps and includes full power-
down mode and fast wake-up for optimal power man-
agement and a high-speed 3-wire serial interface. The
3-wire serial interface directly connects to SPI/QSPI™/
MICROWIRE^® devices without external logic.
Excellent dynamic performance, low voltage, low power,
ease of use, and extremely small package size make this
converter ideal for portable battery-powered data-acquisi-
tion applications, and for other applications that demand
low-power consumption and minimal space.
The MAX11108 is available in an ultra-TQFN (2.1mm x
1.6mm) package, and operates over the -40°C to +125°C
temperature range.
