ADS7841ESQDBQRQ1 from Texas Instruments, in a SSOP-16-150mil. 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 | VCC | power_in | Power supply; the recommended range is 4.75 V to 5.25 V at 5 V nominal or 2.7 V to 3.6 V at 2.7 V nominal. |
| 2 | CH0 | input | Analog input channel 0; the positive input must stay between -0.2 V and VCC + 0.2 V. |
| 3 | CH1 | input | Analog input channel 1; the positive input must stay between -0.2 V and VCC + 0.2 V. |
| 4 | CH2 | input | Analog input channel 2; the positive input must stay between -0.2 V and VCC + 0.2 V. |
| 5 | CH3 | input | Analog input channel 3; the positive input must stay between -0.2 V and VCC + 0.2 V. |
| 6 | COM | input | Ground reference for the analog inputs that sets the zero-code voltage in single-ended mode; connect it to ground or a ground reference point. |
| 7 | SHDN | input | Shutdown input; when low, the device enters a very low-power shutdown mode. |
| 8 | VREF | power_in | Voltage reference input; the reference can range from 0.1 V to VCC. |
| 9 | VCC | power_in | Power supply; the recommended range is 4.75 V to 5.25 V at 5 V nominal or 2.7 V to 3.6 V at 2.7 V nominal. |
| 10 | GND | power_in | Ground connection; the datasheet recommends connecting the GND pin to a clean ground point. |
| 11 | MODE | input | Conversion mode; when low the device always performs a 12-bit conversion, and when high the resolution is set by the MODE bit in the CONTROL byte. |
| 12 | DOUT | output | Serial data output shifted on the falling edge of DCLK; it is high-impedance when CS is high. |
| 13 | BUSY | output | Busy output; it is high-impedance when CS is high. |
| 14 | DIN | input | Serial data input; data is latched on the rising edge of DCLK when CS is low. |
| 15 | CS | input | Chip select input that controls conversion timing and enables the serial input/output register. |
| 16 | DCLK | input | External clock input that runs the SAR conversion process and synchronizes serial data I/O. |
