Single-Supply, Low-Power, 2-Channel, Serial 8-Bit ADCs
General DescriptionThe MAX1117/MAX1118/MAX1119 low-power, 8-bit,
dual-channel, analog-to-digital converters (ADCs) fea-
ture an internal track/hold (T/H) voltage reference
(MAX1117/MAX1119), clock, and serial interface. The
MAX1118 is specified from +2.7V to +5.5V and con-
sumes only 135µA at 100ksps. The MAX1117 is speci-
fied from +2.7V to +3.6V, and the MAX1119 is specified
from +4.5V to +5.5V, each consumes only 175µA at
100ksps.
The full-scale analog input range is determined by the
internal reference of +2.048V (MAX1117) or +4.096V
(MAX1119), or by an externally applied reference rang-
ing from +1V to VDD(MAX1118). All devices feature an
automatic shutdown mode that reduces supply current
to <1µA when the device is not in use. The 3-wire serial
interface directly connects to SPI™, QSPI™, and
MICROWIRE™ devices without external logic.
Conversions up to 100ksps are performed using an
internal clock.
The MAX1117/MAX1118/MAX1119 are available in an
8-pin SOT23 package with a footprint that is only 11%
of an 8-pin plastic DIP.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
