Skyworks Solutions, Inc. Special Purpose Amplifiers SI8935B-IS

The SI8935B-IS is a galvanically isolated delta-sigma modulator designed for voltage sensing applications, featuring a nominal input range of 0 to 2.5 V. It offers excellent linearity with a typical input offset of ¬±0.4 mV and a gain error of ¬±0.05%. The device is optimized for high common-mode transient immunity, rated at 75 kV/¬µs, making it suitable for environments with high-power switching, such as motor drive systems and inverters. The modulator can be clocked externally up to 25 MHz or internally at 10 MHz, depending on the specific configuration. It provides a digital output stream that is proportional to the input voltage, with a typical signal-to-noise ratio (SNR) of 86 dB. The device is available in compact 8-pin SOIC packages and operates over a temperature range of -40 to 125 ¬8C. The SI8935B-IS is recognized for safety with a UL 1577 rating of up to 2.5 kVrms and is compliant with various safety standards. Automotive-grade options are available, ensuring robustness and reliability for automotive applications. This product is suitable for a wide range of applications, including industrial data acquisition, motor control, and battery management systems.
