GENERAL DESCRIPTION
The MAX1117/MAX1118/MAX1119 low-power, 8-bit, dual-channel, analog-to-digital converters (ADCs) feature 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 consumes only 135µA at 100ksps. 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. o Single Supply +2.7V to +3.6V (MAX1117) +2.7V to +5.5V (MAX1118) +4.5V to +5.5V (MAX1119) o Internal Track/Hold: 100kHz Sampling Rate o Internal Reference +2.048V (MAX1117) +4.096V (MAX1119) o Reference Input Range: 0 to VDD (MAX1118) o SPI/QSPI/MICROWIRE-Compatible Serial Interface...
