General Description
Features
The MAX11102/MAX11103/MAX11105/MAX11106/MAX11110 S 2Msps/3Msps Conversion Rate, No Pipeline Delay
MAX11111/MAX11115/MAX11116/MAX11117 are 12-/10-
/8-bit, compact, high-speed, low-power, successive
approximation analog-to-digital converters (ADCs).
These high-performance ADCs include a high-dynamic
range sample-and-hold and a high-speed serial inter-
face. These ADCs accept a full-scale input from 0V to the
Y 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
R _{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
A ^{from the power supply.}
These ADCs operate from a 2.2V to 3.6V supply and
consume only 8.3mW at 3Msps and 6.2mW at 2Msps.
The devices include full power-down mode and fast
IN ^{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-
IM ^{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,
L ^{10-pin FMAX® package, and a 6-pin SOT23 package.}
These devices operate over the -40NC to +125NC tem-
E ^{perature range.}
