ADS7841E 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 input, specified for 2.7V to 5V operation. |
| 2 | CH0 | input | Analog input channel 0; analog inputs are rated from -0.3V to +VCC + 0.3V to GND. |
| 3 | CH1 | input | Analog input channel 1; analog inputs are rated from -0.3V to +VCC + 0.3V to GND. |
| 4 | CH2 | input | Analog input channel 2; analog inputs are rated from -0.3V to +VCC + 0.3V to GND. |
| 5 | CH3 | input | Analog input channel 3; analog inputs are rated from -0.3V to +VCC + 0.3V to GND. |
| 6 | COM | passive | Ground reference for the analog inputs that sets the zero-code voltage in single-ended mode; connect 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 for the converter. |
| 9 | +VCC | power_in | Power supply input (second VCC pin, internally the same supply as pin 1), specified for 2.7V to 5V operation. |
| 10 | GND | power_in | Ground connection for the device; the datasheet recommends a clean ground point. |
| 11 | MODE | input | Conversion mode select; when LOW the device always performs 12-bit conversions, and when HIGH the resolution is set by the MODE bit in the CONTROL byte. |
| 12 | DOUT | tri_state | Serial data output shifted on the falling edge of DCLK; high impedance when CS is HIGH. |
| 13 | BUSY | tri_state | Busy output; high impedance when CS is HIGH. |
| 14 | DIN | input | Serial data input; data is latched on the rising edge of DCLK while 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. |
