# OPA734AID

**Texas Instruments** · Precision Op Amps · SOIC-8

OPA734AID 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 | NC | unconnected | No internal connection (NC = No Connection per page 4 footnote); leave unconnected. |
| 2 | -IN | input | Inverting input; common-mode range is (V−) − 0.1V to (V+) − 1.5V, and inputs swinging more than 0.5V beyond the rails should be limited to 10mA. |
| 3 | +IN | input | Non-inverting input; common-mode range is (V−) − 0.1V to (V+) − 1.5V, and inputs swinging more than 0.5V beyond the rails should be limited to 10mA. |
| 4 | V- | power_in | Negative supply rail (ground for single-supply use); operating supply is 2.7V to 12V total (±1.35V to ±6V). |
| 5 | NC | unconnected | No internal connection (NC = No Connection per page 4 footnote); leave unconnected. |
| 6 | OUT | output | Amplifier output with rail-to-rail swing within 50mV of the rails at RL = 10kΩ; short-circuit current is ±20mA. |
| 7 | V+ | power_in | Positive supply rail; operating range 2.7V to 12V (absolute maximum supply 13.2V). |
| 8 | Enable | input | CMOS-logic shutdown input: at or below (V−) + 0.8V the amplifier is shut down (standby current 9µA max) with output high-impedance, and at or above (V−) + 2V it is active; input bias current is 3µA. |

## CAD (KiCad official)

- Symbol: `OPA734AID`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `opa734aid-etched.step` / `opa734aid-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa734aid.step` / `opa734aid.glb` are the bare package body.
