**Texas Instruments** · Operational Amplifier · SOIC-8

LMH6658MAX 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 | OUT A | output | Output of amplifier A, which is short-circuit protected and can source +80/−90 mA, with short-circuit duration limited to 1.5 ms for VS > 6 V. |
| 2 | -IN A | input | Inverting input of amplifier A, whose input current is limited to ±10 mA and whose differential input voltage is limited to ±2.5 V. |
| 3 | +IN A | input | Noninverting input of amplifier A, whose common-mode range extends 0.5 V below V− and 1.7 V below V+. |
| 4 | V- | power_in | Negative supply; the recommended supply range is 3 V to 12 V (V+ − V−), and pin voltages must stay between V− − 0.8 V and V+ + 0.8 V. |
| 5 | +IN B | input | Noninverting input of amplifier B, whose common-mode range extends 0.5 V below V− and 1.7 V below V+. |
| 6 | -IN B | input | Inverting input of amplifier B, whose input current is limited to ±10 mA and whose differential input voltage is limited to ±2.5 V. |
| 7 | OUT B | output | Output of amplifier B, which is short-circuit protected and can source +80/−90 mA, with short-circuit duration limited to 1.5 ms for VS > 6 V. |
| 8 | V+ | power_in | Positive supply; the recommended supply range is 3 V to 12 V (V+ − V−), with an absolute maximum supply voltage of 12.6 V. |
