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. The MAX1117 is specified 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 ranging 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.

Product Detail

The MAX1117 evaluation system (EV system) is a complete two-channel data-acquisition system consisting of a MAX1117 evaluation kit (EV kit) and a Maxim 68L11DMODULE microcontroller (µC) module. The MAX1117 is a high-speed, 8-bit data-acquisition system. Windows® 95/98 software provides a handy user interface to exercise the MAX1117's features.

Order the complete EV System (MAX1117EVL11) for comprehensive evaluation of the MAX1117 using a personal computer. Order the EV kit (MAX1117EVKIT) if the 68L11DMODULE module has already been purchased with a previous Maxim EV system, or for custom use in other µC-based systems.
