ADC0834CCWMX from Texas Instruments, in a SOIC-14-300mil. 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 | V+ | power_in | Shunt regulator zener input to GND (6.3 to 8.5V breakdown) connected to VCC via a diode; limit current into V+ to 15 mA max with a series resistor. |
| 2 | CS | input | Active-low chip select; must be held low for the entire conversion, and a high level clears all internal registers. |
| 3 | CH0 | input | Analog multiplexer input channel 0, single-ended or differential, range -0.3V to VCC+0.3V. |
| 4 | CH1 | input | Analog multiplexer input channel 1, single-ended or differential, range -0.3V to VCC+0.3V. |
| 5 | CH2 | input | Analog multiplexer input channel 2, single-ended or differential, range -0.3V to VCC+0.3V. |
| 6 | CH3 | input | Analog multiplexer input channel 3, single-ended or differential, range -0.3V to VCC+0.3V. |
| 7 | DGND | power_in | Digital ground. |
| 8 | AGND | power_in | Analog ground; the COM input is internally connected to AGND. |
| 9 | VREF | power_in | Voltage reference input defining the analog input span, typically 3.5 kOhm input resistance, maximum value limited to VCC. |
| 10 | DO | tri_state | Serial data output, TRI-STATE, shifts out conversion result MSB first then LSB first on CLK falling edges. |
| 11 | SARS | output | SAR status output, goes high while a conversion is in progress. |
| 12 | CLK | input | Clock input, 10 kHz to 400 kHz, 40% to 60% duty cycle. |
| 13 | DI | input | Serial data input that shifts the start bit and MUX address into the MUX address register on CLK rising edges. |
| 14 | VCC | power_in | Converter supply, 4.5 VDC to 6.3 VDC operating, 6.5V absolute maximum. |
