TCA9548A I2C Multiplexer with ADS1100 using python and raspberry pi

I would like to use the tca9548a multiplexer from Adafruit:

Together with the ads1100 adc:

on a RPI4. The tca9548 and the ads1100 are recognized fine using the i2c scanner provided by adafruit:

However, I can not use the smbus library to access the adc using this code example:

Because I can not provide the tca[0] object to # Get I2C bus
bus = smbus.SMBus(1)

it only accepts integers. Any ideas how I can use the adafruit library to point to the ads1100 registers?
