The AMC1304L25DWR is a reinforced isolated delta-sigma modulator from Texas Instruments designed for precision current sensing applications. It features a ±250mV peak-to-peak input voltage range, 16-bit resolution, and a maximum modulator sampling rate of 20Msps. The device provides an output data rate of 78kSPS and uses an LVDS serial data interface, enabling robust digital communication across the isolation barrier.
Key electrical characteristics include a typical SNR of 85dB, typical SFDR of -80dB, and a common-mode transient immunity of at least 15kV/µs. The modulator operates from a single 3V to 5.5V supply and includes an on-chip 18V LDO regulator. Offset error is specified at ±50µV or ±100µV maximum depending on input range, with offset drift of 1.3µV/°C maximum; gain error is ±0.2% or ±0.3% maximum with ±40ppm/°C gain drift. Power consumption is typically 58.9mW.
The device is rated for reinforced isolation with 5000Vrms withstand isolation voltage, 1500Vrms working isolation voltage, and 7VPK transient isolation voltage. It provides minimum creepage and clearance of 8.5mm. The AMC1304L25DWR is supplied in a 16-SOIC (0.295", 7.50mm width) surface-mount package measuring 10.3mm x 10.3mm, and is fully specified for operation from -40°C to 125°C. An external 5MHz to 20MHz clock input supports system-level synchronization.
Typical applications include shunt-resistor-based current sensing in motor drives, isolated data acquisition, and industrial field bus communication. The device is pin-compatible within the AMC1304x family, offering flexibility in input voltage range and digital interface options.
