TMS320F28379D: Analog input current leak - comparison to TMS320F280049

Lenio Cacula
Genius 17140 points

Part Number: TMS320F28379D
Other Parts Discussed in Thread: TMS320F280049

When comparing Table 5.6 of the datasheet for TMS320F28379D versus TMS320F280049, we observe that the current leak for analog inputs is an order of magnitude different

TMS320F28379D: Current leak = 2uA

TMS320F280049L Current leak = 0.1uA

Considering that the parts have similar process technology and similar peripherals, I wanted to double check that those numbers are correct.

I appreciate the help!

    Hi Lenio,

    Due to more sensitive characterization methods, we were able to get this number down on the F28004x family of devices. These are indeed using similar technology, so F2837xD family devices likely have better performance than is specified in the datasheet.
