Texas Instruments AMC0303M2510 Delta-Sigma Modulator
Texas Instruments AMC0303M2510 Delta-Sigma Modulator is a galvanically isolated delta-sigma (ΔΣ) modulator with a ±250mV input and internal clock. The input is optimized for connection to low-impedance shunt resistors commonly used for current-sensing applications. This device achieves 12.8 effective bits of resolution or 80dB of dynamic range, at a 39kSPS sample rate. The AMC0303M2510 modulator comes in 8-pin, wide- and narrow-body SOIC packages. This delta sigma modulator is fully specified over the temperature range from -40°C to 125°C. The AMC0303M2510 delta-sigma modulator is ideal for motor drives, photovoltaic inverters, server Power Supply Units (PSU), and energy storage systems.
