I2C Programmable-Gain Amplifier

Slave Address Byte and Address Pins
The slave address byte consists of a 7-bit slave
address plus a R/W bit (see Figure 2). The DS4420’s
slave address is determined by the state of the A0, A1,
and A2 address pins. These pins allow up to eight
DS4420s to reside on the same I2C bus. Address pins
connected to GND result in a ‘0’ in the corresponding
bit position in the slave address. Conversely, address
pins connected to VCC result in a ‘1’ in the correspond-
ing bit positions. For example, the DS4420’s slave
address byte is A0h when A0, A1, and A2 pins are
grounded. I2C communication is described in detail in
the
I2C Serial Interface Description section.
