OPA860IDR from Texas Instruments, in a SOIC-8. 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 | IQ Adjust | passive | External resistor on this pin sets the OTA transconductance, trading quiescent current against bandwidth and gain; the datasheet test conditions use RADJ = 250Ω. |
| 2 | E | bidirectional | OTA emitter terminal, a low-impedance input/output; the datasheet specifies E-input resistance of 10.5 Ω min at +25°C and 12.5 Ω min at 0°C to -40°C. |
| 3 | B | input | OTA base terminal, a high-impedance input with a B-input voltage range of ±4.2 V typ (±3.6 V min over temperature). |
| 4 | V− | power_in | Negative supply rail, −5 V in the datasheet operating configuration; absolute maximum power supply is ±6.5 VDC. |
| 5 | In | input | Input of the closed-loop unity-gain voltage buffer. |
| 6 | Out | output | Output of the closed-loop unity-gain voltage buffer, rated for 60 mA output current. |
| 7 | V+ | power_in | Positive supply rail, +5 V in the datasheet operating configuration; absolute maximum power supply is ±6.5 VDC. |
| 8 | C | output | OTA collector terminal, the bipolar current output of the transconductance amplifier. |
