2Msps/3Msps, Low-Power,
Serial 12-/10-/8-Bit ADCs
General Description
Features
S 2Msps/3Msps Conversion Rate, No Pipeline Delay
S 12-/10-/8-Bit Resolution
The MAX11102/MAX11103/MAX11105/MAX11106/MAX11110
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
power supply or to the reference voltage.
S 1-/2-Channel, Single-Ended Analog Inputs
S Low-Noise 73dB SNR
S Variable I/O: 1.5V to 3.6V (Dual-Channel Only)
Allows the Serial Interface to Connect Directly
to 1.5V, 1.8V, 2.5V, or 3V Digital Systems
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.
S 2.2V to 3.6V Supply Voltage
S Low Power
8.3mW at 3Msps
6.2mW at 2Msps
Very Low Power Consumption at 2.5µA/ksps
S External Reference Input (Dual-Channel Devices Only)
S 1.3µA Power-Down Current
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
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.
S SPI-/QSPI-/MICROWIRE-Compatible Serial
Interface
S 10-Pin, 3mm x 3mm TDFN Package
S 10-Pin, 3mm x 5mm µMAX Package
S 6-Pin, 2.8mm x 2.9mm SOT23 Package
S Wide -40NC to +125NC Operation
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.
