General Description
The MAX110/MAX111 analog-to-digital converters
(ADCs) use an internal auto-calibration technique to
achieve 14-bit resolution plus overrange, with no exter-
nal components. Operating supply current is only
550µA (MAX110) and reduces to 4µA in power-down
mode, making these ADCs ideal for high-resolution bat-
tery-powered or remote-sensing applications. A fast
serial interface simplifies signal routing and opto-isola-
tion, saves microcontroller pins, and offers compatibility
with SPI™, QSPI™, and MICROWIRE™. The MAX110
operates with ±5V supplies, and converts differential
analog signals in the -3V to +3V range. The MAX111
operates with a single +5V supply and converts differ-
ential analog signals in the ±1.5V range, or single-
ended signals in the 0V to +1.5V range.
Internal calibration allows for both offset and gain-error
correction under microprocessor (µP) control. Both
devices are available in space-saving 16-pin DIP and
SO packages, as well as an even smaller 20-pin SSOP
package.
