I used LTC6242 as a voltage follower configuration: - power to IC is 4.2V
- measured V+ to IC is 3.8V
- V- is feedback to Vout, measured about 3.6V
- output is set at high impedance for testing
(Note that I wanted output to be 3.8V)
When the power is at 4.2V, output seems to be saturated at 3.6V even I increased the V+ voltage higher.
Has anyone tested the saturation level of this op amp?
Other than increasing the power supply, any other method?
