MAX11117 are 12-/10-/8-bit, compact, high-speed, low-
power, successive approximation analog-to-digital con-
verters (ADCs). These high-performance ADCs include a
high-dynamic range sample-and-hold and a high-speed
serial interface. These ADCs accept a full-scale input
from 0V to the power supply or to the reference voltage.
The MAX11102/MAX11103/MAX11106/MAX11111 fea-
ture dual, single-ended analog inputs connected to the
ADC core using a 2:1 MUX. The devices also include a
separate supply input for data interface and a dedicated
input for reference voltage. In contrast, the single-chan-
nel devices generate the reference voltage internally
from the power supply.
These
consume only 5.2mW at 3Msps and 3.7mW at
The devices include full power-down mode and fast
wake-up for optimal power management and a high-
speed 3-wire serial interface. The 3-wire serial interface
directly connects to SPIK, QSPIK, and MICROWIREK
devices without external logic.
Excellent dynamic performance, low voltage, low power,
ease of use, and small package size make these con-
verters ideal for portable battery-powered data-acquisi-
tion applications, and for other applications that demand
low-power consumption and minimal space.
These ADCs are available in a 10-pin TDFN package,
10-pin FMAX
These devices operate over the -40NC to +125NC tem-
perature range.
