Texas Instruments AMC0106M05 Precision Delta-Sigma Modulator
Texas Instruments AMC0106M05 Precision Delta-Sigma Modulator has an input voltage range of ±50mV. The isolation barrier separates parts of the system that operate on different common-mode voltage levels. The isolation barrier supports transient overvoltages up to 570VRMS/800VDC and working voltage up to 200VRMS/280VDC.
With a low input voltage range and small package size, the AMC0106M05 is designed for isolated, high-accuracy current sensing in space-constrained applications. The galvanic isolation barrier isolates sensitive control circuitry from switching noise from the power stage and supports high common-mode transients.
The output bitstream is synchronized to the Texas Instruments AMC0106M05 external clock. Combined with a sinc3, OSR 256 filter, the device achieves 16 bits of resolution with a 78kSPS data rate and an 84dB dynamic range. The AMC0106M05 is specified over the extended industrial temperature range of –40°C to +125°C and is available in an 8-pin, 0.65mm pitch VSON package.
