TLC272 Split Supply Solution

Other Parts Discussed in Thread: TLC272


I am currently testing an application that utlizes the TLC272 with a split supply with Vdd=+12V and the GND= -5V to create a negative reference voltage.

It is periodically failing.

The most likely culprits are the following

1. The split supply. (I am less inclined to think this as the supply limits are relative to the imposed GND which in this case is floating)

2. This operates the part  slightly outside its recommend range of 16V and close to the absolute max of 18V.


I appreciate your thoughts.
