SI8936D-AS4R

ADCs/DACs - Special Purpose Overview

The SI8936D-AS4R is an automotive-grade, galvanically isolated delta-sigma modulator designed for voltage measurement applications. It features a single-ended input range of 0 to 2.5 V and integrates a 10 MHz internal oscillator, eliminating the need for external clocking. The device provides high common-mode transient immunity (75 kV/µs) and low offset drift (±0.5 µV/°C). It operates on supply voltages between 3.0 V and 5.5 V with typical power consumption of 7 mA. The component utilizes CMOS isolation technology rated for up to 5.0 kVRMS withstand voltage per UL 1577 standards.

ADCs/DACs - Special Purpose Feature Summary

• Integrated 10 MHz internal DSM clock
• 5.0 kVRMS isolation rating (UL 1577)
• High CMTI of 75 kV/µs
• Automotive-grade AEC-Q100 qualification

ADCs/DACs - Special Purpose Applications

• Automotive on-board chargers
• Battery management systems
• Industrial motor controls
• Renewable energy inverters

ADCs/DACs - Special Purpose Procurement Notes

Verify that the AS4R suffix corresponds to the Wide Body Stretched SOIC package in tape and reel format. Confirm the specific insulation rating associated with the 'D' suffix matches system requirements. Ensure compliance with moisture sensitivity level handling procedures during assembly.

ADCs/DACs - Special Purpose Selection Notes

Select this model when an internal 10 MHz clock is required for the delta-sigma modulator. Compare against Si8935 if an external clock is preferred or Si8937 if a 20 MHz internal clock is needed. Verify that the 0 to 2.5 V input range aligns with the scaled sensor output voltage.

ADCs/DACs - Special Purpose Part Context

This part belongs to the Si893x family of isolated delta-sigma modulators. It shares the same core architecture and pinout as the Si8935 and Si8937, differing primarily in clock source configuration and insulation rating suffixes. The 'S' indicates the Wide Body package variant.

ADCs/DACs - Special Purpose Replacement Considerations

Si8936D-IS4 offers identical electrical performance but uses tube packaging instead of tape and reel.
