Overview

The AD7665AST is an analog To Digital Converter made by Analog Devices in a LQFP-48(7x7) package with 48 pins. -40℃~+85℃ 1 16 2.5LSB 4.75V~5.25V 570kHz 90dB Bipolar input External SAR SPI、Parallel Port Yes LQFP-48(7x7) Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:AD7665ASTRL, from EasyEDA) and its footprint (Package_QFP:LQFP-48_7x7mm_P0.5mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C7455533).

Questions

Is there a KiCad symbol and footprint for the AD7665AST?

Yes. The symbol is EasyEDA_Cloud:AD7665ASTRL and the footprint Package_QFP:LQFP-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 AD7665AST?

LQFP-48(7x7), with 48 pins. Its footprint is drawn on this page.

Where is the AD7665AST datasheet?

Analog Devices publishes it: the Datasheet link on this page opens it.

Where can I order the AD7665AST?

JLCPCB lists it as part C7455533, with 0 in stock; the sellers' links on this page open their listings.

What can replace the AD7665AST?

Parts like it in the library: the AD7671ASTZ by Analog Devices, the ADS7882IPFBR by Texas Instruments, the AD7610BSTZ by Analog Devices and the AD7622BSTZRL by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
