OPA859IDSGR from Texas Instruments, in a WSON-8-EP(2x2). 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 | FB | input | Feedback input; provides direct connection to amplifier output for transimpedance amplifier feedback network configuration. |
| 2 | NC | unconnected | No connection; must remain floating to provide isolation between FB and IN- pins and reduce capacitive coupling. |
| 3 | IN- | input | Inverting input with differential input impedance of 1 GΩ and differential input capacitance of 0.2 pF. |
| 4 | IN+ | input | Non-inverting input with common-mode input impedance of 1 GΩ, common-mode capacitance of 0.62 pF, and common-mode range 0 V to (VS+ - 1.4 V). |
| 5 | VS- | power_in | Negative power supply rail referenced to ground for split-supply or ground for single-supply operation; absolute maximum voltage range 0 V to (VS+ - 5.5 V). |
| 6 | OUT | output | Amplifier output with output voltage high 3.95 V to 4.1 V and low 1.1 V to 1.15 V at VS+ = 5 V, RL = 200Ω; output swing limited to approximately 3 V. |
| 7 | VS+ | power_in | Positive power supply rail; recommended operating voltage range 3.3 V to 5.25 V; total supply voltage (VS+ - VS-) must be 3.3 V to 5.25 V. |
| 8 | PD | input | Power-down input; logic low (< 0.65 V referenced to VS-) disables amplifier and reduces quiescent current to 70 µA to 140 µA; logic high (> 1.5 V) enables normal operation. |
| 9 | Thermal Pad | power_in | Exposed thermal pad; must be soldered to printed circuit board and connected to VS- for proper thermal and mechanical performance. |
