Correct, this is not ideal, but in certain scenarios with limited pins (due to iovoltage groups), we are indeed starting to see this kind of usage model starting to pop up. Tradeoff is in a limit on image quality, but that tends to be acceptable in certain lower cost solutions. -- Regards, Nishanth Menon Key (0xDDB5849D1736249D) / Fingerprint: F8A2 8693 54EB 8232 17A3 1A34 DDB5 849D 1736 249D
