Is there a KiCad symbol and footprint for the HT7705ARWZ?
Yes. The symbol is EasyEDA_Cloud:HT7705ARWZ and the footprint EasyEDA_Cloud:SOIC-16_L10.3-W7.5-P1.27-LS10.3-BL, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the HT7705ARWZ?
WSOP-16, with 16 pins. Its footprint is drawn on this page.
Where is the HT7705ARWZ datasheet?
HTCSEMI publishes it: the Datasheet link on this page opens it.
Where can I order the HT7705ARWZ?
JLCPCB lists it as part C2834480, with 47 in stock; the sellers' links on this page open their listings.
What can replace the HT7705ARWZ?
Parts like it in the library: the AD7124-8BCPZ by Analog Devices, the TM7707 by TM, the MS7705 by Hangzhou Ruimeng Tech and the ADS1218Y/250 by Texas Instruments. Check their datasheets: a part that fits the footprint may still differ in its ratings.
