AMC1304M05QDWQ1

ADCs/DACs - Special Purpose Overview

The AMC1304M05QDWQ1 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 a maximum clock frequency of 20.1 MHz. The device operates on dual power supplies ranging from 3 V to 5.5 V for the digital side and 4 V to 18 V for the analog side. Key performance metrics include a differential nonlinearity (DNL) of 0.99 LSB, an integral nonlinearity (INL) of 1.5 LSB, and a gain error of -0.02%. It consumes 58.9 mW of power and functions within a temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Feature Summary

• AEC-Q100 qualified for automotive reliability requirements
• Reinforced isolation capability for high-voltage safety
• Sigma-delta modulation structure with 16-bit effective resolution
• Low DNL (0.99 LSB) and INL (1.5 LSB) for precision measurement

ADCs/DACs - Special Purpose Applications

• Automotive current sensing systems
• High-side or low-side current monitoring
• Motor control feedback loops
• Battery management system (BMS) measurements

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix QDWQ1 against the manufacturer's latest datasheet to confirm package type and qualification status. Ensure compatibility with the target PCB footprint for the SOIC-16 package. Check for moisture sensitivity level (MSL) handling requirements during assembly. Confirm that the design supports the required input voltage range and isolation ratings for the specific application environment.

ADCs/DACs - Special Purpose Selection Notes

Select this component when reinforced isolation and high precision are required in automotive environments. Compare DNL and INL specifications against other isolated modulators if higher linearity is needed. Consider the power consumption of 58.9 mW relative to thermal constraints. Verify that the serial interface matches the microcontroller or DSP capabilities in the system design.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1304M05 series of isolated modulators from Texas Instruments. It is distinct from the AMC1305 series by its specific input range and interface characteristics. The 'Q' suffix indicates automotive qualification, while 'DW' denotes the SOIC-16 package. It serves as a key component for translating analog signals across isolation barriers in demanding automotive electronics.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include AMC1304M05DWQ1 (non-automotive grade) or AMC1304M05QDWRQ1 (tape and reel packaging). For different input ranges, consider the AMC1305M25 series. Verify pinout compatibility and electrical parameters before substituting.
