Product Overview: Texas Instruments AMC1304M25QDWRQ1

The Texas Instruments AMC1304M25QDWRQ1 is a precision, delta-sigma (ΔΣ) modulator with the output separated from the input circuitry by a silicon dioxide (SiO2) barrier that is highly resistant to magnetic interference. This isolation barrier has been certified to provide basic galvanic isolation of up to 4000 V PEAK according to VDE V 0884-10 and UL1577 standards.

Designed to capture high-precision analog signals in harsh industrial environments, the AMC1304M25QDWRQ1 boasts a fixed data rate of 20Mbps and an input voltage range of ±250mV (differential). Its low offset error and gain error contribute to its high accuracy, making it suitable for applications such as motor control, grid infrastructure, and industrial equipment where precise measurements are crucial.

One of the key features of this product is its reinforced isolation design, which not only protects against high voltage but also ensures robust operation in environments with high electromagnetic interference (EMI). The device's integrated digital filter simplifies system design by performing sinc3 filtering of the modulator bitstream, which can be easily interfaced with a microcontroller or digital signal processor.

The AMC1304M25QDWRQ1 operates over the extended industrial temperature range of -40°C to +125°C, ensuring reliable performance in a variety of temperature conditions. The device is offered in a wide-body 16-pin SOIC package, providing additional space for the isolation barrier and making it easier to handle during the manufacturing process.

Key specifications include:

• Reinforced isolation of 4000 V PEAK
• ±250 mV input voltage range
• Fixed 20-MHz data rate
• Low offset error and gain error
• Extended industrial temperature range: -40°C to +125°C
