The AMC1305M25DWR is a high-precision, reinforced isolated delta-sigma modulator from Texas Instruments, designed for accurate current sensing via shunt resistors. It offers 16-bit resolution with a sampling rate of 78 kSPS and a ±250 mV input voltage range. The device integrates a capacitive double isolation barrier, providing reinforced isolation of 7000 Vpk per DIN VDE V 0884-11 and 5000 Vrms per UL1577 for 1 minute. This makes it suitable for applications requiring high safety and noise immunity.
Key electrical specifications include a typical offset error of ±50 µV (max ±150 µV), offset drift of 1.3 µV/°C, gain error of ±0.3% max, and gain drift of ±40 ppm/°C. The device operates from a single 3V to 5.5V supply and supports an external clock input from 5 MHz to 20 MHz for system-level synchronization. Transient immunity is a minimum of 15 kV/µs.
The modulator output is a CMOS serial data interface, providing direct digital output proportional to the analog input. It is fully specified over the extended industrial temperature range of -40°C to 125°C. The part is housed in a surface-mount 16-SOIC package (0.295", 7.50mm width) with NiPdAu lead finish, and is available in large tape-and-reel carrier (2000 units per reel).
