How many ADS7828 Analog to Digital Converters can be connected via I2C?

Hello. How many of “ADS7828 Analog to Digital Converter 16-Channel 12-Bit with I2C Interface” boards can be connected to I2C interface? It looks to me that maximum is 2 since there are only 4 addresses. We need to control 8 of these boards. Could we use the I2C multiplexer to do it? Thank you.

Yes, you can use I2C mux.
we have two kinds.

I always recommend going with 8 channel.
