Built for continuous operation with low failure rates.
If your circuit derives its primary power from a noisy DC/DC step-down buck converter, high-frequency switching noise can easily bleed into your sensitive components. The DC=E2H provides 70dB of rejection at 10kHz, acting as an active low-pass electronic filter to isolate downstream logic from upstream noise. 3. Comprehensive On-Chip Protection If your circuit derives its primary power from
Regulated Output Voltage Supply (Fixed 1.8V for this variant). Key Electrical Specifications & Operating Limits
Power Supply Input Pin. Requires a minimum input voltage of 2.5V up to 5.5V. GND Ground Reference. 3 EN
– Active-high logic input. Pulling this pin below the shutdown threshold drops current consumption near zero.
Whether you are isolating a PLC input, floating a battery monitor, or breaking a ground loop in a sensor network, the DC E2H series offers a reliable, cost-effective solution. But only if you read the fine print.
