Questions
Is there a KiCad symbol and footprint for the DAC8734SPFB?
Yes. The symbol is EasyEDA_Cloud:DAC8734SPFB and the footprint Package_QFP:TQFP-48_7x7mm_P0.5mm, both drawn on this page. PCBKit places them on a board for you when you design with it.
What package is the DAC8734SPFB?
TQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.
Where is the DAC8734SPFB datasheet?
Texas Instruments publishes it: the Datasheet link on this page opens it.
Where can I order the DAC8734SPFB?
JLCPCB lists it as part C1555661, with 31 in stock; the sellers' links on this page open their listings.
What can replace the DAC8734SPFB?
Parts like it in the library: the HT7123ARQZ by HTCSEMI, the ADV7125JSTZ330 by Analog Devices, the ADV7123KSTZ50 by Analog Devices and the AK4493SEQ-L by Asahi Kasei Microdevices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
