Overview

The ADS7831P is an analog To Digital Converter made by Texas Instruments in a DIP-28 package with 28 pins. -40℃~+85℃ 1 12 1LSB 1LSB 600kHz 72dB Bipolar input、Bipolar power supply Built-in Built-in No Not supported Parallel Port SAR ±2.5V DIP-28 Analog to Digital Converters (ADC).

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:ADS7831P, from EasyEDA) and its footprint (Package_DIP:DIP-28_W8.89mm_SMDSocket_LongPads, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C7210815).

Questions

Is there a KiCad symbol and footprint for the ADS7831P?

Yes. The symbol is EasyEDA_Cloud:ADS7831P and the footprint Package_DIP:DIP-28_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 ADS7831P?

DIP-28, with 28 pins. Its footprint is drawn on this page.

Where is the ADS7831P datasheet?

Texas Instruments publishes it: the Datasheet link on this page opens it.

Where can I order the ADS7831P?

JLCPCB lists it as part C7210815, with 0 in stock; the sellers' links on this page open their listings.

What can replace the ADS7831P?

Parts like it in the library: the AD1674KNZ by Analog Devices, the AD574AKNZ by Analog Devices, the AD674BJNZ by Analog Devices and the AD7721AN by Analog Devices. Check their datasheets: a part that fits the footprint may still differ in its ratings.
