ADC121S051CIMFX

Texas Instruments · Analog To Digital Converters (ADC) · SOT-23-6

ADC121S051CIMFX from Texas Instruments, in a SOT-23-6. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 VA power_in Positive analog supply pin, to be connected to a quiet +2.7V to +5.25V source and bypassed to GND with a 1 µF capacitor and a 0.1 µF monolithic capacitor located within 1 cm of the power pin.
2 GND power_in Ground return for the supply and signals.
3 VIN power_in Analog input that can range from 0V to VA.
4 SCLK input Digital clock input that directly controls the conversion and readout processes.
5 SDATA output Digital data output; the datasheet's pin table gives no separate electrical limit for this pin.
6 CS input Chip select; a conversion process begins on the falling edge of CS.

CAD (KiCad official)

  • Symbol: ADC121S051CIMFX
  • Footprint: Package_TO_SOT_SMD:SOT-23-6
  • 3D model: SOT-23-6 (KiCad packages3D, STEP)
  • 3D model files: adc121s051cimfx-etched.step / adc121s051cimfx-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); adc121s051cimfx.step / adc121s051cimfx.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:
