ADCs/DACs - Special Purpose Procurement Notes

Verify the specific ordering suffix 'M25' against the manufacturer's official orderable addendum or datasheet revision history. Standard documentation references the 'M05' variant; confirm if 'M25' denotes a distinct pinout, speed grade, or packaging variation to ensure correct component identification during procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component for applications requiring direct connection to shunt resistors with differential inputs up to ±50 mV. Ensure the system utilizes an external digital filter capable of decimating the bitstream at 78 kSPS to achieve 16-bit resolution. Verify that the isolation requirements meet the 7070 VPEAK rating and that the operating environment stays within the specified -40°C to +125°C temperature range.

ADCs/DACs - Special Purpose Part Context

This device belongs to the AMC1306 family of reinforced isolated delta-sigma modulators designed for high-voltage automotive power electronics.
