# LMH6654MFX

**Texas Instruments** · Operational Amplifier · SOT-23-5

LMH6654MFX from Texas Instruments, in a SOT-23-5. 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 | OUTPUT | output | Amplifier output, which swings from −3.6 V to 3.4 V with RL = 100 Ω and is unity-gain stable. |
| 2 | V- | power_in | Negative supply rail; the recommended supply range is ±2.5 V to ±6.0 V (V+ − V−), and the absolute maximum total supply is 13.2 V. |
| 3 | +IN | input | Non-inverting input with a common-mode range of −5.15 V to +3.7 V; input pins must stay between V− − 0.5 V and V+ + 0.5 V (absolute maximum). |
| 4 | -IN | input | Inverting input with the same input voltage limits as the non-inverting input, and a differential input absolute maximum of ±1.2 V. |
| 5 | V+ | power_in | Positive supply rail; the recommended supply range is ±2.5 V to ±6.0 V (V+ − V−), and the absolute maximum total supply is 13.2 V. |
