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 external components. Operating supply current is only 550µA (MAX110) and reduces to 4µA in power-down mode, making these ADCs ideal for high-resolution battery-powered or remote-sensing applications. A fast serial interface simplifies signal routing and opto-isolation, 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. Internal calibration allows for both offset and gain-error correction under microprocessor (µP) control. ____________________________Features o o o o o Single +5V Supply (MAX111) Two Differential Input Channels 14-Bit Resolution Plus Sign and Overrange 0.03% Linearity (MAX110) 0.05% Linearity (MAX111) Low Power Consumption: 550µA (MAX110) 640µA (MAX111) 4µA Shutdown...
