DS25048B-page 1 MCP3903 Features • Six Synchronous Sampling 16/24-bit Resolution Delta-Sigma A/D Converters with Proprietary Multi-Bit Architecture • 91 dB SINAD, -100 dBc Total Harmonic Distortion (THD) (up to 35th harmonic), 102 dB Spurious-free Dynamic Range (SFDR) for Each Channel • Programmable Data Rate up to 64 ksps • Ultra Low-Power Shutdown Mode with <2 μA • -115 dB Crosstalk Between any Two Channels • Low Drift Internal Voltage Reference: 5 ppm/°C • Differential Voltage Reference Input Pins • High Gain PGA on Each Channel (up to 32 V/V) • Phase Delay Compensation Between Each Pair of Channels with 1 μs Time Resolution • High-Speed Addressable 10 MHz SPI Interface with Mode 0,0 and 1,1 Compatibility • Independent Analog and Digital Power Supplies 4.5V - 5.5V AVDD, 2.7V - 3.6V DVDD • Available in Small 28-lead SSOP Package • Extended Temperature Range: -40°C to +125°C Applications • Energy Metering and Power Measurement • Portable Instrumentation • Medical and Power Monitoring Description The MCP3903 is a six-channel Analog Front End (AFE) containing three pairs made out of two synchronous sampling Delta-Sigma Analog-to-Digital Converters (ADC) with PGA, a phase delay compensation block, internal voltage reference, and high-speed 10 MHz SPI compatible serial interface. The converters contain a proprietary dithering algorithm for reduced idle tones and improved THD. The internal register map contains 24-bit wide ADC data words, a modulator output register as well as six 24-bit writable control registers to program gain, over-sampling ratio, phase, resolution, dithering, shut-down, reset and several communication features. The communication is largely simplified with various Continuous Read modes that can be accessed by the Direct Memory Access (DMA) of an MCU and with separate Data Ready pins that can directly be connected to the Interrupt Request (IRQ) input of an MCU. The MCP3903 is capable of interfacing to a large variety of voltage and current sensors including shunts, current transformers, Rogowski coils, and Hall-effect sensors.
