Product details

12-bit multiplying DAC in 20-PLCC

The PM7645FPC is a 12-bit buffered multiplying DAC from Analog Devices, designed for applications requiring a current-unbuffered output and an external reference. Its multiplying architecture allows the reference voltage to vary over a wide range, making it suitable for digitally controlled gain or attenuation in signal chains. The device integrates a single D/A converter with a parallel data interface, accepting 12-bit digital words to produce an output current proportional to the applied reference. The buffered output stage maintains linearity across the full code range.

Linearity and temperature grade

The 20-PLCC package (J-Lead, 9x9 mm body) provides a compact footprint for surface-mount assembly, with the J-bend leads offering good solder-joint inspection access. The supplier device package is 20-PLCC (9x9).

Frequently asked questions

What is the closest functional second-source to PM7645FPC?

The AD5447YRUZ-REEL7 is a dual-channel 12-bit multiplying DAC with a similar R-2R architecture and parallel interface, but it provides two converters in a single package versus the PM7645FPC's single channel. The AD5447 also operates over a wider temperature range (-40°C to 125°C) and is RoHS-compliant. Pin compatibility should be verified against the target PCB layout.
