Analog (A-type/mV/4-20mA): Continuous voltage or current output. Direct to ADC or PLC input. Lower latency, simpler for experienced engineers. Ideal for industrial PLCs, automotive ECUs, traditional control systems. Digital I2C (D-type): I2C bus output, 1.8-3.6V supply. Built-in ADC+calibration. Lower power for battery devices. Direct MCU read without external ADC. Ideal for IoT, smart home, wearables, battery-powered devices. Both use the same in-house MEMS chip - choose based on your system architecture.
