Microchip's MCP3911 features two 24-bit, ΔΣ ADCs that operate at 3 V with industry-leading accuracy of 94.5 dB SINAD and -106.5 dB THD. This provides better energy-meter and power-monitoring performance by accurately measuring from start-up to maximum current, and enables faster calibration during production. Four different power modes offer the flexibility of enabling either extremely low-power designs, as low as 0.8 mA per channel, or designs with higher-speed signals and harmonic content. The extended temperature range allows operation from -40°C to +125°C.
