AMC1311QDWVRQ1 from Texas Instruments, in a SOIC-8-300mil. 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 | VDD1 | power_in | High-side (input-side) power supply, 3.0 V to 5.5 V referenced to GND1. Bypass to GND1 with a low-ESR ceramic (typically 100 nF close to the pin plus a bulk 1-10 µF). |
| 2 | VINP | input | Non-inverting (positive) high-impedance analog input. Linear differential input range is ±2 V (full-scale ±2 V) relative to VINN, with a typical differential input impedance of ~1.25 GΩ. Referenced to GND1. |
| 3 | VINN | input | Inverting (negative) high-impedance analog input, typically tied to the low-side reference of the sensed node. Common-mode input range and ±2 V differential range are referenced to GND1. |
| 4 | GND1 | power_in | High-side (input-side) analog ground reference. All VDD1, VINP and VINN signals are referenced to this pin; it is isolated from GND2 across the reinforced isolation barrier. |
| 5 | GND2 | power_in | Low-side (output-side) ground reference for VDD2, VOUTP and VOUTN. Isolated from GND1 by the reinforced capacitive isolation barrier (up to 7 kVpk). |
| 6 | VOUTN | output | Inverting (negative) side of the differential analog output, referenced to GND2. Output common-mode is nominally VDD2/2 and the full-scale differential output swing is ±2 V. Drive to a downstream differential ADC input or an instrumentation amplifier. |
| 7 | VOUTP | output | Non-inverting (positive) side of the differential analog output, referenced to GND2. Together with VOUTN forms the ±2 V full-scale differential output with a VDD2/2 common-mode. |
| 8 | VDD2 | power_in | Low-side (output-side) power supply, 3.0 V to 5.5 V referenced to GND2. Bypass to GND2 with a low-ESR ceramic (typically 100 nF close to the pin plus a bulk 1-10 µF). |
