LMH6503MAX from Texas Instruments, in a SOIC-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 pin; the datasheet characterizes the part at VS = ±5V. |
| 2 | VG | input | Gain control voltage input with high input impedance (70kΩ, 1.3pF); gain control range is −1V to +1V relative to the GND pin (pin 11). |
| 3 | +VIN | input | Non-inverting differential input (pins 3 and 6 share a ±2.0V minimum common-mode input range, 750kΩ input resistance, 5pF input capacitance); the unused input can be tied to ground for single-ended operation. |
| 4 | +RG | passive | Gain-setting resistor RG connection (pins 4 and 5), with maximum RG current of ±1.70mA minimum. |
| 5 | -RG | passive | Gain-setting resistor RG connection (pins 4 and 5), with maximum RG current of ±1.70mA minimum. |
| 6 | -VIN | input | Inverting differential input (pins 3 and 6 have 11µA typical bias current and ±0.34V minimum differential input voltage across them). |
| 7 | V- | power_in | Negative supply pin; the datasheet characterizes the part at VS = ±5V. |
| 8 | V- | power_in | Negative supply pin; the datasheet characterizes the part at VS = ±5V. |
| 9 | VREF | power_in | Reference pin of the output stage as labeled in the connection diagram; the datasheet text provided gives no further limits. |
| 10 | VOUT | output | Output of the current feedback op amp, able to drive ±3.2V typical into 100Ω with ±75mA minimum output current. |
| 11 | GND | power_in | Ground pin, the reference potential for the −1V to +1V gain control range; tied to a virtual half supply in single-supply operation. |
| 12 | I- | input | Inverting input of the output current feedback op amp as labeled in the connection diagram; the datasheet text provided gives no further limits. |
| 13 | NC | unconnected | No connect pin. |
| 14 | V+ | power_in | Positive supply pin; the datasheet characterizes the part at VS = ±5V. |
