I have a DAC that I am trying to design a circuit with. The goal of the circuit is to check whether the DAC is working or not, plain and simple.
The DAC in question is the PMI PM-7545 12-bit DAC. A link to the datasheet is below:
I can power the chip, but I'm not sure how to set up a simple circuit to check whether it is working or not. All of the tests that I read about seem to use something like a Raspberry Pi to drive the 12 inputs and read the output on a multimeter, but I don't have anything like the Pi that can drive each of the 12 inputs. What kind of simple circuit is recommended to check whether a DAC is working or not?
The datasheet of the 7545 contains a diagram of a burn-in circuit. I never heard of this term before, but from what I researched, a burn-in circuit is used to test the operation of the circuit under long periods of time to ensure functionality over time before the device fails. Looking at it, I'm unsure whether it would ensure that it is working, since the outputs are driven to ground, and the inputs are driven to high-rated voltage.
EDIT: Thanks to Glenn W9IQ for his answer. Below is my proposed testing schematic:
The inputs would vary depending on what I'm trying to get at the output, so depending on the bits, they would be at ground or 5 volts, and the switch would just be a wire that I would short to GND to enable it.
