AMC1305M25QDWRQ1

ADCs/DACs - Special Purpose Overview

The AMC1305M25QDWRQ1 is a reinforced isolated modulator designed for automotive applications, certified to AEC-Q100 standards. It features a ±250mV differential input range and utilizes a CMOS serial interface for data transmission. The device operates with a 16-bit resolution and supports a maximum sampling rate of 78 kSPS. Power consumption is typically 36.1 mW, with analog supply voltages ranging from 4.5 V to 5.5 V and digital supplies from 3 V to 5.5 V. Housed in a 16-pin SOIC package, it provides high common-mode transient immunity (CMTI) of 15 kV/μs and an isolation rating of 7 kV peak.

ADCs/DACs - Special Purpose Feature Summary

• AEC-Q100 qualified for automotive reliability
• Reinforced isolation with 7 kV peak rating
• 16-bit resolution at 78 kSPS sampling rate
• CMOS serial interface compatible with standard logic

ADCs/DACs - Special Purpose Applications

• Automotive current sensing using shunt resistors
• Isolated gate driver feedback loops
• On-board charger (OBC) monitoring systems
• DC-DC converter control circuits

ADCs/DACs - Special Purpose Procurement Notes

Verify the Q suffix indicates automotive grade qualification and the R suffix denotes tape-and-reel packaging. Confirm the M25 designation corresponds to the ±250mV input range. Ensure compatibility with 16-SOIC footprint requirements during procurement planning.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a CMOS interface is required instead of LVDS or SPI options within the AMC1305 family. The ±250mV input range suits high-current shunt measurements. Compare power dissipation specifications against thermal constraints in enclosed automotive enclosures.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1305 series of isolated modulators. It shares architectural similarities with non-automotive variants like the AMC1305M25DWR but includes specific automotive reliability testing. The 'Q' suffix distinguishes it as an automotive-grade product compliant with AEC-Q100 standards.

ADCs/DACs - Special Purpose Replacement Considerations

Direct functional substitutes include other AMC1305 variants with matching input ranges and interfaces, such as the AMC1305M25DWR for non-automotive use. For automotive replacements, verify equivalent CMTI ratings and isolation voltage levels.
