LMH6503MTX from Texas Instruments, in a TSSOP-14. 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 | V+ | power_in | Positive supply voltage, ±5V nominal. |
| 2 | VG | input | Gain control input, −1V to +1V range relative to GND for gain adjustment. |
| 3 | +VIN | input | Positive differential input, common mode voltage ±1.8V to ±2.2V. |
| 4 | +RG | passive | Positive feedback resistor node for external gain resistor connection. |
| 5 | -RG | passive | Negative feedback resistor node for external gain resistor connection. |
| 6 | -VIN | input | Negative differential input, common mode voltage ±1.8V to ±2.2V. |
| 7 | V- | power_in | Negative supply voltage, ±5V nominal. |
| 8 | V- | power_in | Negative supply voltage, ±5V nominal. |
| 9 | VREF | power_in | Reference voltage output for external bias networks. |
| 10 | VOUT | output | Output voltage, ±3.2V maximum with 100Ω load. |
| 11 | GND | power_in | Ground reference, virtual half-supply point for single-supply operation. |
| 12 | I- | output | Output current feedback node supporting ±90mA maximum output current. |
| 13 | NC | unconnected | No connection, should remain floating. |
| 14 | V+ | power_in | Positive supply voltage, ±5V nominal. |
