MCP 3910A1-E/SS


The MCP3910 is a 3-V dual-channel analogue front end (AFE) containing two synchronous sampling delta-sigma analogue-to-digital converters (ADC), two PGAs, phase delay compensation block, internal voltage reference, modulator output block and a high-speed 20-MHz SPI compatible serial interface. For poly-phase shunt-based energy meters, the MCP3910 2-wire serial interface greatly reduces system costs by requiring only a single bi-directional isolator per phase. The MCP3910 can be used with a variety of voltage and current sensors, including shunts, current transformers, Rogowski coils and Hall effect sensors

• Flexible serial interface that includes both SPI and a simple two-wire interface ideal for polyphase shunt energy meters
• 93.5 dB SINAD, -107 dBc THD, 112 dBFS SFDR
• 2.7 - 3.6 V AVDD, DVDD
• Programmable data rate up to 125 ksps — 4 MHz maximum sampling frequency
• Oversampling ratio up to 4096
• Ultra low-power shutdown mode with < 2 µA
• -122 dB crosstalk between the two channels
• Low drift 1.2-V internal voltage reference: 9 ppm/°C
• Differential voltage reference input pins
• High gain PGA on each channel (up to 32 V/V)
• Phase delay compensation with 1-µs time resolution
• Separate modulator output pins for each channel
• Separate data ready PIN for easy synchronisation

Technical data:
• Dynamic range: 1000:1
• Voltage drift ppm: 9
• Supply voltage (AVdd): 2.7 - 3.6 V
• Supply voltage (DVdd): 2.7 - 3.6 V
