THS4509QRGTRQ1 from Texas Instruments, in a VQFN-16-EP(3x3). 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 | NC | unconnected | No internal connection. |
| 2 | VIN- | power_in | Inverting amplifier input. |
| 3 | VOUT+ | output | Noninverted amplifier output. |
| 4 | CM | input | Common-mode voltage input. |
| 5 | VS+ | power_in | Positive amplifier power-supply input. |
| 6 | VS+ | power_in | Positive amplifier power-supply input. |
| 7 | VS+ | power_in | Positive amplifier power-supply input. |
| 8 | VS+ | power_in | Positive amplifier power-supply input. |
| 9 | CM | input | Common-mode voltage input. |
| 10 | VOUT- | output | Inverted amplifier output. |
| 11 | VIN+ | power_in | Noninverting amplifier input. |
| 12 | PD | input | Power down; logic low puts part into low-power mode, logic high or open for normal operation. |
| 13 | VS- | power_in | Negative amplifier power supply input. |
| 14 | VS- | power_in | Negative amplifier power supply input. |
| 15 | VS- | power_in | Negative amplifier power supply input. |
| 16 | VS- | power_in | Negative amplifier power supply input. |
| 17 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
