ADX111QAMSOP10

analogysemi · Analog To Digital Converters (ADC) · MSOP-10

ADX111QAMSOP10 from analogysemi, in a MSOP-10. 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 ADDR input I2C slave address select pin, connected to GND, VDD, SDA or SCL to choose one of four addresses (1001000, 1001001, 1001010, 1001011), and its state is sampled continuously.
2 ALERT/RDY output Open-drain comparator output or conversion-ready output that requires a pull-up resistor to VDD, and may be left floating or weakly pulled up if unused.
3 GND power_in Ground reference for the device.
4 AIN0 passive Analog input 0, which must be kept within GND - 0.3 V to VDD + 0.3 V to avoid forward-biasing the ESD diodes.
5 AIN1 passive Analog input 1, which must be kept within GND - 0.3 V to VDD + 0.3 V to avoid forward-biasing the ESD diodes.
6 AIN2 passive Analog input 2, which must be kept within GND - 0.3 V to VDD + 0.3 V to avoid forward-biasing the ESD diodes.
7 AIN3 passive Analog input 3, which must be kept within GND - 0.3 V to VDD + 0.3 V to avoid forward-biasing the ESD diodes.
8 VDD power_in Power supply, which must be decoupled to GND with a 0.1 µF capacitor.
9 SDA bidirectional Serial data line that transmits and receives data, and requires an external pull-up resistor because the I2C driver is open-drain.
10 SCL input Serial clock input that locks data on SDA, and the device never drives this line low (no clock stretching).
