MAX110 Datasheet | Maxim Integrated

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 ponents. 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 patibility 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 differential analog signals in the ±1.5V range, or singleended 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. ____________________________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 Current Up to 50 Conversions/sec 50Hz/60Hz Rejection Auto-Calibration Mode No External ponents Required 16-Pin DIP/SO, 20-Pin SSOP MAX110/MAX111 o o o o o Ordering Information PART MAX110ACPE TEMP.
