AMC1204BDWV Description

Short technical summary and product information.

The AMC1204BDWV is a precision, basic isolated delta-sigma modulator from Texas Instruments designed for current-sensing applications using shunt resistors. It features a ±250-mV peak-to-peak input voltage range optimized for direct connection to shunt resistors, and a 20-MHz external clock input for synchronization.

 

Key electrical specifications include a sampling rate of 0.078 Msps, signal-to-noise ratio of 84 dB minimum, spurious-free dynamic range of 78 dB typical, and total harmonic distortion of -80 dB maximum. DC precision includes integral nonlinearity of ±8 LSB maximum and gain error of ±2% maximum. The device consumes 88 mW typical from a 2.7V to 5.5V supply.

 

The modulator provides basic isolation with a withstand isolation voltage of 3000 Vrms, working isolation voltage of 849 Vrms, and transient isolation of 4250 Vpk. Common-mode transient immunity is 15 kV/µs. The device is available in an 8-pin SOIC (0.295", 7.50mm Width) surface-mount package and operates over the extended industrial temperature range of -40°C to 125°C.
