Product details

The AD7774KP is an 8-bit combined ADC and DAC from Analog Devices, integrating four analog I/O channels in a single 28-lead PLCC package.

Temperature grade and package fit

Housed in a 28-PLCC (J-Lead) with a body size of 11.51 mm × 11.51 mm, the surface-mount package requires reflow soldering and is compatible with standard PLCC-28 footprints.

Note that this part is RoHS non-compliant; it contains lead in the solder finish and is exempt from RoHS restrictions for certain applications. Buyers requiring RoHS compliance should evaluate the AD7774KN through-hole variant or a newer-generation converter.

Frequently asked questions

Is AD7774KP RoHS compliant?

No, the AD7774KP is marked as RoHS non-compliant. It uses a lead-based solder finish and is intended for applications where RoHS exemption applies.

What is the closest functional alternative to AD7774KP?

The AD7774KN is the through-hole (DIP) version of the same die — same 8-bit resolution, 4-channel count, parallel interface, and temperature range. It drops into designs that use a DIP socket but requires a board change from the PLCC footprint.
