ADS8320EB

Texas Instruments · Analog To Digital Converters (ADC) · VSSOP-8

ADS8320EB from Texas Instruments, in a VSSOP-8. 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 VREF power_in Reference input that sets the analog input range; it must be between 0.5 V and VCC.
2 +In input Noninverting analog input; the +In input must remain within GND - 100 mV to VCC + 100 mV for specified linearity, and the differential input +In - (-In) spans 0 V to VREF.
3 -In input Inverting analog input to be connected to ground or a remote ground sense point; its range is limited to -0.1 V to 1 V (-0.1 V to 0.5 V at a 2.7-V supply).
4 GND power_in Ground reference for the device.
5 CS/SHDN input Chip select when LOW and shutdown mode when HIGH; digital inputs accept logic levels up to 5.5 V regardless of VCC.
6 DOUT output Serial output of the 16-bit conversion result, valid on the falling edge of DCLOCK, swinging 0 V to VCC, and tri-stating after the MSB is repeated once CS is taken HIGH.
7 DCLOCK input Data clock that synchronizes the serial data transfer and determines conversion speed, with an external clock range of 24 kHz to 2.4 MHz and minimum high and low times of 200 ns at VCC of 2.7 V or greater.
8 +VCC power_in Power supply, specified for 2.7 V to 5.25 V (operable from 2 V to 5.25 V) and to be decoupled close to the pin.

CAD (KiCad official)

  • Symbol: ADS8320EB
  • Footprint: Package_SO:VSSOP-8_3x3mm_P0.65mm
  • 3D model: VSSOP-8, generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 1.1 mm tall, datasheet A, max). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions come from the datasheet drawing where it was read and are defaults otherwise (see provenance.model_3d_generated), not the manufacturer's CAD (STEP)
  • 3D model files: ads8320eb-2k5-etched.step / ads8320eb-2k5-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); ads8320eb-2k5.step / ads8320eb-2k5.glb are the bare package body.
