The I2C address bits for the MCP3427 and MCP3428
are selected by using two external I2C address
selection pins (Adr0 and Adr1). The user can configure
the device to one of eight available addresses by
connecting these two address selection pins to VDD,
VSS or float. The I
2C address bits of the MCP3426 are
programmed at the factory during production.
The MCP3426 is available in 8-pin SOIC, DFN, and
MSOP packages. The MCP3427 is available in 10-pin
DFN, and MSOP packages. The MCP3428 is available
in 14-pin SOIC and TSSOP packages.
