Hi ADI Expert, 
 
 We're comparing these two current sense amp and have some questions need your help to check : 
 
 1. Does LTC6102 include internal LDO as AD8612 shown in block diagram? 
 2. Is possible to have AD8219's PSRR curve from 100Hz~1 MHz '?

Hello Henry, 
 1. The LTC6102 has an internally regulated supply which is used for internally biasing the device. Generally, Vreg will charge to approximately 4.5V below the supply. However, this is not intended to be used for external power. 
 I am not sure which document you are referring the AD8612 from. Could you specify which figure you are talking about? 
 2. I will check if this data is available. 
 Thanks, 
 Kris)
