MCP3903-Slide15

In summary, the MCP3903 features six delta-sigma A/D converters with adjustable 16- and 24-bit resolution modes. These ADCs are highly accurate, and each channel features a programmable gain amplifier with gain of up to thirty-two. The MCP3903 is capable of measuring high frequency signals with an adjustable sample rate of up to 64ksps. A compensation block between each converter channel pair corrects for phase delay. The MCP3903 also features a low temperature coefficient internal voltage reference. Communication with an MCU is via SPI, and the device operates down to 2.7V for compatibility with 3V microcontrollers.
