AMC1304M05QDWRQ1

ADCs/DACs - Special Purpose Overview

The AMC1304M05QDWRQ1 is a reinforced isolated sigma-delta modulator designed for automotive applications, certified under AEC-Q100 standards. It features a single channel with 16-bit resolution and supports sampling rates up to 78 kS/s. The device operates on digital power supplies ranging from 3 V to 5.5 V and analog supplies from 4.5 V to 5.5 V. It utilizes a CMOS serial interface for data output and is housed in a 16-SOIC package. The component functions within an operating temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Reinforced isolation barrier for high-voltage safety
• 16-bit resolution with 78 kS/s maximum sampling rate
• CMOS serial digital output interface

ADCs/DACs - Special Purpose Applications

• Automotive motor control systems
• Current sensing in electric vehicle inverters
• Isolated signal acquisition in automotive power electronics

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix QDWRQ1 against the manufacturer's official datasheet to confirm pinout compatibility and isolation ratings. Ensure that the supply voltage constraints (3V–5.5V digital, 4.5V–5.5V analog) align with the target system design before procurement.

ADCs/DACs - Special Purpose Selection Notes

Select this component when reinforced isolation and automotive qualification are required for current sensing. Compare DNL (0.99 LSB) and INL (1.5 LSB) specifications against system accuracy needs. Consider the 16-SOIC package dimensions for PCB layout constraints relative to alternative packages like WSON or SOIC-8.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC130x family of isolated modulators from Texas Instruments. It shares architectural similarities with the AMC1305 and AMC1306 series but differs in input range and interface type. The 'M05' designation typically indicates a specific gain configuration within the product line.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements include other AMC1304 variants with different suffixes (e.g., DWQ1 vs DWRQ1) which may differ only in packaging format. Cross-family substitution requires verifying isolation voltage levels and interface compatibility.
