# ADS8324E

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

ADS8324E 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 can be any voltage from 500mV to VCC/2. |
| 2 | +In | input | Non-inverting analog input, which should always remain within GND - 100mV to VCC + 100mV for linearity to meet specification. |
| 3 | -In | input | Inverting analog input, which should always remain within GND - 100mV to 2V for linearity to meet specification. |
| 4 | GND | power_in | Ground reference; the datasheet recommends placing it on a clean ground point, away from microcontroller ground connections. |
| 5 | CS/SHDN | input | Chip select when LOW and shutdown mode when HIGH; CS must be taken HIGH after a conversion to place DOUT in tri-state. |
| 6 | DOUT | output | Serial data output, MSB first, valid on the DCLOCK rising edge; it is enabled after the fifth falling DCLOCK edge following CS falling and swings from 0V to VCC. |
| 7 | DCLOCK | input | Data clock that synchronizes serial data transfer and sets conversion speed; the external clock may range from 24kHz to 1.2MHz with minimum high and low times of 200ns. |
| 8 | +VCC | power_in | Power supply; specified performance at 1.8V with an operating range of 1.8V to 3.6V. |

## CAD (KiCad official)

- Symbol: `ADS8324E`
- Footprint: `Package_SO:VSSOP-8_2.3x2mm_P0.5mm`
- 3D model: VSSOP-8 (KiCad packages3D, STEP)
- 3D model files: `ads8324e-etched.step` / `ads8324e-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `ads8324e.step` / `ads8324e.glb` are the bare package body.
