Before I buy this chip I think its AD7147, but the surface of the chip writes 7147ACPZ-1 #IM 45632. I wonder its AD7147 or AD7147-1.
Very grateful for all answers!
Hi Majh, The photo you attached does show a device with the branding of an AD7147-1.
Hi Maurice, thanks for your reply. I bought it online and the website told me it is AD7147, as the fig shows.
Maybe I should go back change my PCB board. Anyway, much thanks for your reply!
Hi Majh, For guaranteed quality always purchase ICs from official vendors.
