I was almost sure I had, but what I used was the AD5300 (SPI interface).

I have confirmed the correct command sequence going into the chip with a
logic analyzer. In sending a 0x55 byte, I have confirmed the bytes going to
the chip are 0x18, 0x25, and 0x50 (in that order). The output remains

Well, the 2 in 0x25 is setting 100k impedance powerdown mode. You should
see 0x18 (address + write) 0x05 0x50. The upper nybble of the first data
word needs to be 0. 1, 2 and 3 would all be powerdown modes.
