SLVSFE3B November 2020 – May 2021 TPS2661
Select the ±Vs supplies for TPS2661x devices higher than absolute analog input voltage for ADC inputs.
TPS2661x devices have under-voltage and over-voltage protection on OUT pin and the internal FETs are turned
off if OUT pin has voltage higher than +Vs or lower than –Vs.
TPS2661x devices also have under-voltage protection on IN pin and and the internal FETs are turned off if IN pin has a voltage lower than –Vs. See External Power Supply for using unipolar or bipolar supply with TPS2661x.
