SI8932B-ISR

Special Purpose Amplifiers Overview

The Skyworks SI8932B-ISR is a galvanically isolated analog amplifier featuring a single channel with a single-ended output. It operates within a supply voltage range of 3 V to 5.5 V and supports an input signal range up to 2.5 V. The device provides a bandwidth of 600 kHz, typical gain error of ±0.06%, and input offset voltage of 0.16 mV. It utilizes CMOS isolation technology for high common-mode transient immunity and is housed in an 8-pin SOIC package.

Special Purpose Amplifiers Procurement Notes

Verify the specific insulation rating associated with the 'B' suffix against the required safety standards. Confirm the 'R' suffix indicates reel packaging if applicable. Ensure the component meets RoHS compliance requirements. Check moisture sensitivity level specifications before soldering assembly to prevent damage.

Special Purpose Amplifiers Selection Notes

Select this model when a single-ended output is required for isolated voltage sensing applications. Compare performance against the differential output Si8931 variant if noise rejection is critical. Verify that the 2.5 kV RMS insulation rating aligns with system safety requirements. Consider thermal characteristics for high ambient temperature environments.
