What this 10-bit multiplying DAC brings to the board
The PM7533H is a CMOS 10-bit multiplying DAC from Analog Devices, built with a multiplying architecture that accepts an external reference and delivers a voltage-unbuffered output. It settles to within ±1 LSB INL/DNL in 800 ns, making it a fit for control-loop or waveform-generation paths where the reference sets the full-scale range. The part runs on a single supply rail — both analog and digital sides share a tight 14.85 V to 15.15 V window — and communicates over a parallel data interface. The differential output gives you a clean signal pair for driving into a difference amplifier or a transformer-coupled stage.
Shipped in Bulk (loose parts in an antistatic bag or tube, depending on the factory fill), the PM7533H is a through-hole part. No hot-air station needed — it drops into a standard DIP footprint and can be swapped on site with a basic soldering iron and a desoldering pump. The pinout is well marked on the body; orientation is unambiguous with the notch and pin-1 dot. The supply rails are non-negotiable: both VDD and VSS must stay within 14.85 V to 15.15 V. Decouple each pin with a 0.1 µF ceramic right at the package; a 10 µF tantalum per rail on the board side handles the bulk charge delivery during the 800 ns settling transient.
Analog Devices lists the PM7533H as Active.
