# SM73201IMM

**Texas Instruments** · Analog To Digital Converters (ADCs) · VSSOP-10-0.5mm

SM73201IMM from Texas Instruments, in a VSSOP-10-0.5mm. 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_in | External voltage reference input, which must be between +0.5V and VA (+0.5V < VREF < VA). |
| 2 | +IN | input | Non-inverting analog input of the true differential input pair, with an analog input voltage range of 0V to VA. |
| 3 | -IN | input | Inverting analog input of the true differential input pair, with an analog input voltage range of 0V to VA. |
| 4 | GND | power_in | Ground reference for the device; all voltages are measured with respect to GND = 0V. |
| 5 | GND | power_in | Ground reference for the device; all voltages are measured with respect to GND = 0V. |
| 6 | CS | input | Active-low chip select (Chip Select Bar) for the serial interface. |
| 7 | DOUT | output | Serial data output, binary 2's complement and SPI compatible. |
| 8 | SCLK | input | Serial clock input, operated at 1 MHz to 5 MHz clock frequency per the operating ratings. |
| 9 | VIO | power_in | Digital input/output supply, printed in the pin table as +2.7V < VREF < +5.5V, while the operating ratings give VIO as +2.7V to +5.5V. |
| 10 | VA | power_in | Analog supply, printed in the pin table as +4.5V < VREF < +5.5V, while the operating ratings give VA as +4.5V to +5.5V. |
