# ADUM3195BRQZ

**Analog Devices** · Isolation Amplifiers · QSOP-16

ADUM3195BRQZ from Analog Devices, in a QSOP-16. 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 | VDD1 | power_in | Side 1 supply voltage, 4.5 V to 5.5 V; connect a 0.1 µF and a 1 µF capacitor between VDD1 and GND1. |
| 2 | GND1 | power_in | Ground reference for Side 1. |
| 3 | NIC | unconnected | Not internally connected; connect to VDD1, GND1, or leave floating. |
| 4 | VREF1 | power_out | Side 1 reference output voltage; the maximum capacitance on this pin (CREFOUT1) must not exceed 15 pF. |
| 5 | NIC | unconnected | Not internally connected; connect to VDD1, GND1, or leave floating. |
| 6 | VOUT1 | output | Isolated output voltage; with the input op amp in buffer configuration it follows VIN+ with a typical gain of 1. |
| 7 | NC | unconnected | No connect; connect this pin to GND1 and do not leave it floating. |
| 8 | GND1 | power_in | Ground reference for Side 1. |
| 9 | GND2 | power_in | Ground reference for Side 2 (pins 9 to 16). |
| 10 | VOUT2 | output | Output of the input op amp. |
| 11 | VIN− | power_in | Inverting input of the op amp. |
| 12 | VIN+ | power_in | Noninverting input of the op amp; the linear input common-mode range is 0.25 V to VDD2 − 0.7 V. |
| 13 | VREF2 | power_out | Side 2 reference output voltage; the maximum capacitance on this pin (CREFOUT) must not exceed 22 nF. |
| 14 | NC | unconnected | No connect; connect this pin to GND2 and do not leave it floating. |
| 15 | GND2 | power_in | Ground reference for Side 2. |
| 16 | VDD2 | power_in | Side 2 supply voltage, 4.5 V to 5.5 V; the datasheet text says to connect a 0.1 µF and a 1 µF capacitor between VDD1 and GND1 here, which appears to be a typo for VDD2 and GND2. |
