Is there a KiCad symbol and footprint for the HT7705ANZ?
Yes. The symbol is EasyEDA_Cloud:HT7705ARWZ and the footprint Package_DIP:DIP-16_W8.89mm_SMDSocket_LongPads, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7705ANZ?
DIP-16, with 16 pins. Its footprint is drawn on this page.
Where is the HT7705ANZ datasheet?
HTCSEMI publishes it: the Datasheet link on this page opens it.
Where can I order the HT7705ANZ?
JLCPCB lists it as part C2834424, with 42 in stock; the sellers' links on this page open their listings.
What can replace the HT7705ANZ?
Parts like it in the library: the XD7705B by XINLUDA, the MCP3008-I/P by Microchip Technology, the MCP3208-CI/P by Microchip Technology and the MCP3208-BI/P by Microchip Technology. Check their datasheets: a part that fits the footprint may still differ in its ratings.
