ADS7835EB from Texas Instruments, in a VSSOP-8. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.
Pinout
| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | VREF | power_out | Reference voltage output; internal 2.5V buffered reference drives the CDAC and can be bypassed with 0.1µF ceramic and 2.2µF tantalum capacitors. |
| 2 | AIN | input | Analog input accepting ±2.5V range (-VREF to +VREF) with internal 2.5V reference; input resistance during conversion (CONV=LOW) is 2kΩ. |
| 3 | GND | power_in | Ground (VSS) reference. |
| 4 | GND | power_in | Ground (VSS) reference. |
| 5 | CONV | input | Convert input controlling sample/hold mode transition, conversion initiation, serial data transfer start, data format selection (MSB-first or LSB-first), and power-down mode activation. |
| 6 | DATA | output | Serial data output transmitting 12-bit conversion result most significant bit first with each bit valid on rising edge of CLK; can transmit LSB-first by controlling CONV. |
| 7 | CLK | input | Clock input synchronizing serial data transfer and determining conversion speed; clock period minimum 125ns with minimum HIGH and LOW times of 50ns. |
| 8 | +VCC | power_in | Power supply (5V, range 4.75V to 5.25V); decouple with 0.1µF ceramic and 10µF tantalum capacitors. |
