Active quad 8-bit multiplying DAC in 28-DIP
The DAC8408BIHP: Each of the four DACs accepts an 8-bit parallel data word and an external reference voltage, making this part a direct fit for applications that need multiple analog output channels from a single chip — process control trim pots, ATE pin drivers, or multichannel waveform generation where board space is tight.
Parametric fit: INL, settling, and supply rails
This means the DAC holds monotonicity across the whole operating envelope, so a closed-loop control system won't see unexpected output reversals at temperature extremes. The 250 ns settling time to ½ LSB means the DAC can update at roughly 4 MSPS per channel in a pipelined system, though the parallel bus limits aggregate throughput to the host's write cycle.
Package and field-swap reality
Housed in a 28-pin PDIP (0.600-inch wide body), this DAC is a through-hole part — no hot-air station needed. A standard IC extractor and a socketed or soldered DIP footprint gets it swapped on a bench or in the field. The 0.100-inch pitch is forgiving for hand soldering, and the wide body gives good mechanical stability in a socket. The bulk packaging means it ships in tubes or trays, not tape-and-reel — fine for prototyping or repair stock, but a pick-and-place line would need tube feeders or a tray handler.
