Overview

The ADS7881IPFBT is an analog To Digital Converter made by Texas Instruments in a TQFP-48(7x7) package with 48 pins. -40℃~+85℃ 1 12 1LSB 2.7V~5.25V、4.75V~5.25V 25ppm/℃ 4MHz 71dB No Parallel port TQFP-48(7x7) Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (EasyEDA_Cloud:ADS7881IPFBT, from EasyEDA) and its footprint (Package_QFP:TQFP-48_7x7mm_P0.5mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1542861).
