For applications requiring a low profile, the DIP package provides a height of just 0.350". High Accuracy: With a maximum nonlinearity of ± 0.025% for the AD202K/AD204K (± 0.05% for the AD202J/AD204J) and low drift over temperature, the AD202 and AD204 provide high isolation without loss of signal integrity. Low Power: Power consumption of 35 mW (AD204) and 75 mW (AD202) over the full signal range makes these isolators ideal for use in applications with large channel counts or tight power budgets. Wide Bandwidth: The AD204’s full-power bandwidth of 5 kHz makes it useful for wideband signals. It is also effective in applications like control loops, where limited bandwidth could result in instability. Excellent Common-Mode Perf……
