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 ADCs operate from a 2.2V to 3.6V supply and
consume only 5.2mW at 3Msps and 3.7mW at 2Msps.
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 SPI, QSPIK, and MICROWIRE®
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® package, and a 6-pin SOT23 package.
These devices operate over the -40NC to +125NC tem-
perature range.
