Other Parts Discussed in Thread: ADS1015,
We are currently using an ADS1015, due to a low supply we would like to change to a TLA2024.
In our circuit this chip is powered by 3v3 and the I2C bus has 4k7 pullups to 5V. The old chip(ADS1015) worked like this without any problem. The new one (TLA2024) does not.
If i lower the I2C bus voltage to 3v3 the TLA2024 works (power == 3v3 and bus level == 3v3)
If i increase the power to 5V the TLA2024 works (power ==5V and bus level == 5V)
it just does not work when the bus is at 5V and the chip is at 3v3.
Unfortunately, i cant change this in the product.
In the datasheet it does not say the I2C bus should be at a certain level from VCC. It just says GND to 5.5V.
Do you know if this chip shouldn't work like this?
Thanks in advance
