MAX22000ALB+

MAX22000 is an industrial configurable analogue I/O. It is an industrial-grade configurable analogue input/output device that can be configured on-the-fly in software as a voltage input or output, or current input or output. Additional inputs are available to measure other analogue signals. The ADC and DAC can individually choose between an internal or an external reference. It supports the ADC with a low-noise programmable gain amplifier (PGA), with high-voltage and low-voltage input ranges to support RTD and thermocouple measurements. Additional auxiliary inputs are provided to measure cold junction temperatures on-board. It communicates through a high speed 20MHz SPI bus for all configuration and management information, as well as for conversion results. Application includes distributed control systems, process control, programmable logic controllers, programmable automation controllers.

• 24bits ADC resolution, 18bits DAC resolution
• 6 analogue inputs/1 analogue output, software configurable for voltage and current mode
• Two auxiliary ADC inputs for cold junction measurements
• RTD input mode in 2, 3, or 4-wire configurations
• Thermocouple input mode, six GPIOs, 20MHz SPI interface
• Robustness, ±36V protection on all analogue I/O ports
• Overcurrent protection, thermal shutdown
• Undervoltage interrupt on all high voltage supplies
• CRC detection, open detection on all analogue inputs, 1kV HBM protection on all pins
• 64 pin LGA package, operating temperature range from -40 to +125°C
