description:the max1108/max1109 low-power, 8-bit, dual-channel, analog-to-digital converters (adcs) feature an internal track/hold (t/h) voltage reference, clock, and serial inter- face. the max1108 is specified from 2.7v to 3.6v and consumes only 105µa. the max1109 is specified from 4.5v to 5.5v and consumes only 130µa. the analog inputs are software configurable, allowing unipolar/bipolar and single-ended/differential operation; battery monitor- ing capability is also included. the full-scale analog input range is determined by the internal reference of 2.048v (max1108) or 4.096v (max1109), or by an externally applied reference rang- ing from 1v to vdd. the max1108/max1109 also feature a software power-down mode that reduces power con- sumption to 0.5µa when the device is not in use. the 4-wire serial interface directly connects to spi™, qspi™, and microwire™ devices without external logic. conversions up to 50ksps are performed using either the internal clock or an external serial-interface clock. the max1108 and max1109 are available in a 10-pin µmax package with a footprint that is just 20% of an 8-pin plastic dip.
