What is the difference between these 3 part numbers:
LDC1612DNTR
LDC1612QDNTRQ1
LDC1612QDNTTQ1

Hi @Jon, Let’s start with:

TRQ1 vs TTQ1, that’s TI’s part extension for the order size…

  • LDC1612QDNTRQ1 = 4,500 units
  • LDC1612QDNTTQ1 = 250 units

Next, the Q, on these parts, that signifies: Qualified for Automotive Applications (AEC-Q100)

Hi @RobertCNelson, thanks for the reply.
In other words, in regards to PCB layout, they are interchangeable?

Hi @Jon, sorry i don’t know your specific application. But if the PCB design required the “Q” part, i’d really stick with that.
