# ADS7835E

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

ADS7835E 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_out | Reference output; decouple to ground with a 0.1µF ceramic capacitor and a 2.2µF tantalum capacitor. |
| 2 | AIN | input | Analog input with a ±2.5V input range. |
| 3 | GND | power_in | Ground. |
| 4 | GND | power_in | Ground. |
| 5 | CONV | input | Convert input that controls the sample/hold mode, start of conversion, start of serial data transfer, type of serial transfer, and power-down mode. |
| 6 | DATA | output | Serial data output; the 12-bit conversion result is transmitted MSB first, with each bit valid on the rising edge of CLK. |
| 7 | CLK | input | Clock input that synchronizes the serial data transfer and determines the conversion speed. |
| 8 | +VCC | power_in | Power supply, specified at 4.75V to 5.25V; decouple to ground with a 0.1µF ceramic capacitor and a 10µF tantalum capacitor. |
