Product Overview: Texas Instruments AMC1305L25DW

The AMC1305L25DW by Texas Instruments is a precision, delta-sigma (ΔΣ) modulator that converts an analog input signal into a high-speed, single-bit data stream, with on-chip digital isolation based on TI's capacitive isolation technology. This product is designed to measure the shunt voltage across a current-sensing resistor or other low-level signals in motor control, green energy, and other industrial applications.

Key Features

• High Accuracy: The AMC1305L25DW boasts a high linearity of 24 bits with no missing codes and an effective number of bits (ENOB) of typically 14 bits at a 10kHz signal bandwidth.
• Integrated Digital Isolation: The device features a 5kVrms reinforced isolation barrier, which provides safety and robustness against high voltage environments and reduces system-level cost and complexity.
• High Oversampling Ratio: With an oversampling ratio of 16 bits and a modulator clock of 10MHz, it ensures high-resolution signal acquisition.
• Wide Temperature Range: It operates over an industrial temperature range of -40°C to +125°C, making it suitable for harsh environments.
• Low Power Consumption: The low-power design minimizes thermal issues and power loss, which is critical for industrial applications.

Applications

The AMC1305L25DW is ideal for use in a variety of applications, including:

• Motor control systems, such as inverters and servo drives.
• Power monitoring in renewable energy systems like solar inverters and wind turbines.
• Industrial process control and automation systems.
• Power supplies and protection devices.

Product Specifications
