The MCP3564 Analog-to-Digital Converter utilizes an oversampling Delta-Sigma architecture to achieve a 24-bit resolution.

The MCP3564 offers eight single-ended and four differential analog input channels with a programmable gain stage with gain factors from 1/3x to 64x. In addition, the device has the option for differential reference voltage input. It also includes an internal oscillator, an internal temperature sensor and a burnout current source used for open/short circuit detection of external sensors.

When using differential inputs, the input signal is defined by Equation 3.
