10-bit resolution in a multiplying DAC core
The AD7522JQ is a 10-bit multiplying DAC with a voltage-buffered output, built on a CMOS converter architecture. The multiplying topology means the reference input can be an AC signal — the output is the product of the digital code and the reference voltage, making it suitable for digitally controlled attenuators or function generators where the reference varies. Single-ended output (no differential) and a single D/A converter per package keep the signal chain simple for single-supply systems. The 10-bit resolution provides 1024 discrete output steps — adequate for many industrial control and instrumentation loops where 12-bit or higher would be overkill.
28-CDIP ceramic package — through-hole, high-reliability
Housed in a 28-lead ceramic dual-in-line package (CDIP) with 0.600-inch row spacing, the AD7522JQ is a through-hole device. The ceramic body offers better hermeticity and thermal cycling performance than plastic DIPs, which is why it remains common in military, aerospace, and industrial modules that still use socketed or wave-soldered boards. If your BOM calls for a wider range, the AD7522 family includes industrial-temperature-suffix variants.
Active lifecycle, RoHS non-compliant — legacy tin-lead finish
Because it is an active catalog part, sourcing is straightforward through authorized distribution.
