# ADCS7478AIMFE

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

ADCS7478AIMFE 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 | VDD | power_in | Positive supply pin, to be connected to a quiet 2.7 V to 5.25 V source and bypassed to GND with 0.1 µF and 1 µF monolithic capacitors placed within 1 cm of the pin, since the device uses this supply as its reference. |
| 2 | GND | power_in | Ground return for the supply. |
| 3 | VIN | power_in | Analog input whose signal can range from 0 V to VDD. |
| 4 | SCLK | input | Digital clock input with a frequency range of 10 kHz to 20 MHz (performance ensured at 20 MHz) that directly controls the conversion and readout processes. |
| 5 | SDATA | output | Digital data output; the output words are clocked out of this pin by SCLK. |
| 6 | CS | input | Chip select; a conversion process begins on the falling edge of CS. |
