MCP3911 Two-Channel Analog Front End

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.

Features
  • Two synchronous sampling 16- and 24-bit resolution ΔΣ A/D converters
  • 94.5 dB SINAD, -106.5 dBc total harmonic distortion (THD) (up to 35th harmonic), 111 dB SFDR for each channel
  • 2.7 V to 3.6 V AVDD, DVDD
Applications
  • Energy metering and power measurement
  • Automotive
  • Portable instrumentation
  • Medical and power monitoring
  • Audio / voice recognition
