AMC1204DWR Description

Short technical summary and product information.

The AMC1204DWR is a 16-bit, 1-channel isolated delta-sigma modulator from Texas Instruments designed for precision current sensing applications. It accepts a ±250 mV peak-to-peak input voltage range, making it ideal for shunt resistor measurements. The device achieves a maximum sample rate of 0.078 Msps and provides typical SNR of -80 dB and SFDR of 78 dB, with a typical power consumption of 88 mW.

 

The modulator offers basic isolation with a withstand isolation voltage of 3000 Vrms, working isolation voltage of 849 Vrms, and transient isolation voltage of 4.25 VPK. It features a minimum common-mode transient immunity of 15 kV/µs, ensuring reliable operation in noisy environments. The device operates from a 5V supply (3.3V optional) and is specified over an extended industrial temperature range of -40°C to 125°C.

 

The AMC1204DWR is housed in a 16-SOIC (0.295", 7.50mm Width) surface-mount package, with a minimum creepage and clearance of 8.5 mm. It supports a serial data interface and is suitable for isolated current sensing in motor drives, power supplies, and industrial automation systems. The device is catalog rated and complies with RoHS3 requirements (unverified).
