Аналого-цифровые преобразователи (АЦП) MAX110ACWE+

АЦП , 14 бит, 50 выборок/с, Дифференциальный, SPI, Биполярный (+/-), 4.75 В

The MAX110ACWE+ from Maxim Integrated Products is a low cost, 2-channel, ±14bit serial ADC in 16 pin WSOIC package. The analogue to digital converter (ADC) uses an internal auto-calibration technique to achieve 14bit resolution plus overrange with no external components. Operating supply current is only 550µA and reduces to 4µA in power-down mode making this ADC 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 analogue signals in the -3V to +3V range. Internal calibration allows for both offset and gain-error correction under microprocessor (µP) control. Typical applications include process control, weigh scales, panel meters, data acquisition systems and temperature measurement.
