General Description
The 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 135
μ
A 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 V
DD
(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.
