The AMC1100DWVR from Texas Instruments is a precision isolation amplifier with a galvanic isolation barrier rated at 4250 VPEAK. It features a fixed gain of 8, 250mV input range, and operates from a single 5V supply on the high side. The SOIC-8 DWV package provides 8mm creepage and clearance, making it ideal for shunt-based current sensing in motor drives and power converters.<\/p>\n

With a fixed gain of 8 and +\/-250mV input range, it directly interfaces with low-value shunt resistors. The device achieves 0.1% max nonlinearity and 60 kHz bandwidth, while the high common-mode transient immunity ensures reliable operation in noisy switching environments. The SOIC-8 DWV package provides reinforced isolation certified to UL, CSA, and IEC standards.","working_principle":"The AMC1100DWVR uses a sigma-delta modulator on the high-voltage side to digitize the analog input signal, which is transmitted across a capacitive isolation barrier to the low-voltage side. A second-order modulator converts the input into a 1-bit digital stream at 10 MHz. The isolation barrier uses silicon dioxide capacitors for galvanic isolation. On the low side, a digital filter reconstructs the analog output with fixed gain of 8. The separate supply domains ensure complete galvanic isolation between the sensed circuit and the measurement system.","pin_description":"
