12-bit multiplying DAC in a 16-DIP — what the specs mean for your BOM
The PM7543GP is a 12-bit buffered multiplying DAC built around an R-2R ladder architecture, delivering a current-unbuffered output with differential capability. The 380 ns settling time means this part updates a new analog value in under 400 ns — fast enough for closed-loop control loops or waveform generation in the audio band, but not for video-rate reconstruction. The serial data interface keeps pin count low on a 16-pin DIP, which simplifies layout but limits throughput compared to a parallel interface. The commercial temperature range of 0°C to 70°C restricts it to indoor, temperature-controlled environments — not suitable for automotive or industrial enclosures without active cooling.
Package and board-fit — through-hole 16-DIP
Housed in a 16-lead PDIP (0.300-inch body width) with through-hole mounting. The 0.100-inch pitch is breadboard- and protoboard-friendly, and the 16-DIP footprint is a standard socketable package — no special reflow profile needed.
