Texas Instruments AMC0106M25 Delta-Sigma Modulator

Texas Instruments AMC0106M25 Delta-Sigma Modulator delivers 16-bit resolution, ±250mV input functionally isolated modulators with an external lock for current sensing. This modulator features 88dB dynamic range, ensuring precise current and voltage measurements in demanding environments. The AMC0106M25 delta-sigma modulator, with a small package size and low input voltage range, the device is designed for high accuracy, isolated current sensing in space-constrained applications. This device operates at -40°C to 125°C extended industrial temperature range. The AMC0106M25 is available in an 8-pin, 0.65mm pitch VSON package. This modulator is ideal for 48V motor drives, 48V frequency inverters, analog input modules, and power supplies.
