AMC1305M05QDWQ1

ADCs/DACs - Special Purpose Overview

The AMC1305M05QDWQ1 is a single-channel, automotive-grade reinforced isolated sigma-delta modulator manufactured by Texas Instruments. It features a ±50-mV input range and operates with digital supply voltages between 3 V and 5.5 V. The device provides 16-bit resolution at a sampling rate of 78 kSPS. Key performance metrics include a differential nonlinearity (DNL) of 0.99 LSB, integral nonlinearity (INL) of 1.5 LSB, and a gain error of -0.02%. It consumes 36.1 mW of power and functions within an operating temperature range of -40°C to +125°C.

ADCs/DACs - Special Purpose Procurement Notes

Verify the specific suffix 'QDWQ1' against official Texas Instruments documentation to confirm package type and qualification status. Ensure compatibility with system isolation requirements and input voltage ranges before integration.

ADCs/DACs - Special Purpose Selection Notes

Select this component when a high-precision, low-power isolated modulator with a small ±50-mV input range is required. Compare DNL/INL specifications against other AMC1305 variants if higher linearity or different input ranges are needed.

ADCs/DACs - Special Purpose Part Context

This part belongs to the AMC1305 family of isolated modulators. It shares the same core architecture as the AMC1305M25 but differs in input range and interface configuration. The Q1 suffix denotes automotive qualification.

ADCs/DACs - Special Purpose Replacement Considerations

Direct replacements within the same family include the AMC1305M05QDWRQ1. Verify pinout and electrical parameters match before substitution.
