Analog Devices · I2C Isolators · SOIC-16-300mil

ADUM2250ARWZ-RL from Analog Devices, in a SOIC-16-300mil. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 GND1 power_in Ground 1. Ground reference for Isolator Side 1. Pin 1 and Pin 7 are internally connected and should both be tied to a common ground.
2 NC unconnected No Connect. Leave floating or tie as per application requirements.
3 VDD1 power_in Supply Voltage for Side 1, 3.0 V to 5.5 V. Bypass to GND1 with 0.01 uF to 0.1 uF capacitor.
4 NC unconnected No Connect.
5 SDA1 bidirectional I2C Data Input/Output, Side 1. Open-drain bidirectional data line for Side 1 of the isolated I2C bus; requires an external pull-up resistor to VDD1.
6 SCL1 bidirectional I2C Clock Input/Output, Side 1. Open-drain bidirectional clock line for Side 1 of the isolated I2C bus; requires an external pull-up resistor to VDD1.
7 GND1 power_in Ground 1. Ground reference for Isolator Side 1. Pin 1 and Pin 7 are internally connected and should both be tied to a common ground.
8 NC unconnected No Connect.
9 GND2 power_in Ground 2. Isolated ground reference for Isolator Side 2. Pin 9 and Pin 16 are internally connected and should both be tied to a common ground.
10 NC unconnected No Connect.
11 SCL2 bidirectional I2C Clock Input/Output, Side 2. Open-drain bidirectional clock line for Side 2 of the isolated I2C bus; requires an external pull-up resistor to VDD2. Fully I2C compliant.
12 SDA2 bidirectional I2C Data Input/Output, Side 2. Open-drain bidirectional data line for Side 2 of the isolated I2C bus; requires an external pull-up resistor to VDD2. Fully I2C compliant.
13 NC unconnected No Connect.
14 VDD2 power_in Supply Voltage for Side 2, 3.0 V to 5.5 V. Bypass to GND2 with 0.01 uF to 0.1 uF capacitor.
15 NC unconnected No Connect.
16 GND2 power_in Ground 2. Isolated ground reference for Isolator Side 2. Pin 9 and Pin 16 are internally connected and should both be tied to a common ground.
