# ADC161S626CIMMX

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

ADC161S626CIMMX 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 | Voltage reference input, which must satisfy 0.5 V < VREF < VA. |
| 2 | +IN | input | Non-inverting analog input; analog input pins operate from 0 V to VA, with differential input voltage between −VREF and +VREF. |
| 3 | -IN | input | Inverting analog input; analog input pins operate from 0 V to VA, with differential input voltage between −VREF and +VREF. |
| 4 | GND | power_in | Power ground; all voltages are measured with respect to GND = 0 V. |
| 5 | GND | power_in | Power ground; all voltages are measured with respect to GND = 0 V. |
| 6 | CS | input | Chip select bar (active low) digital input; digital input pins operate over 0 V to VIO. |
| 7 | DOUT | output | Serial data output, binary two's complement and SPI compatible. |
| 8 | SCLK | input | Serial clock digital input; the specified clock frequency range is 1 MHz to 5 MHz. |
| 9 | VIO | power_in | Digital input/output power supply, 2.7 V to 5.5 V per the recommended operating conditions. |
| 10 | VA | power_in | Analog power supply, 4.5 V to 5.5 V per the recommended operating conditions. |
