# LMH6732MA

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

LMH6732MA 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 | N/C | unconnected | Not connected; the datasheet lists this pin as N/C in the 8-pin SOIC connection diagram. |
| 2 | -IN | input | Inverting input of the op amp; the datasheet notes that negative input current means current flowing out of the device. |
| 3 | +IN | input | Non-inverting input; the datasheet specifies a common-mode input range of ±2.2 V and an input resistance of 46 MΩ (typical) at VS = ±5 V. |
| 4 | V- | power_in | Negative power supply pin; the datasheet characterizes the device at VS = ±5 V. |
| 5 | RP | passive | Supply-current set pin; a single resistor from this pin sets ICC over a range of more than 10 to 1 (the datasheet uses RP = 412 kΩ for ICC = 1 mA). |
| 6 | OUT | output | Amplifier output; the datasheet specifies output current of ±6 mA (min) to ±9 mA (typ) in closed loop. |
| 7 | V+ | power_in | Positive power supply pin; the datasheet characterizes the device at VS = ±5 V. |
| 8 | N/C | unconnected | Not connected; the datasheet lists this pin as N/C in the 8-pin SOIC connection diagram. |
