Overview

The ADS7040IDCU is an analog To Digital Converter made by Texas Instruments in a VSSOP-8-0.65mm package with 8 pins. -40℃~+125℃ 0.5LSB 1 1.65V~3.6V 1MHz 8 SPI VSSOP-8-0.65mm Analog to Digital Converters (ADC) ROHS.

PCBKit's library has its KiCad symbol (Analog_ADC:ADS7040xDCU, from KiCad's library) and its footprint (Package_SO:VSSOP-8_3x3mm_P0.65mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C1847961).
