# OPA2363AIRSVR

**Texas Instruments** · Operational Amplifier · UQFN-16(1.8x2.6)

OPA2363AIRSVR from Texas Instruments, in a UQFN-16(1.8x2.6). 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; the pin may be left floating. |
| 2 | NC | unconnected | No internal connection; the pin may be left floating. |
| 3 | NC | unconnected | No internal connection; the pin may be left floating. |
| 4 | NC | unconnected | No internal connection; the pin may be left floating. |
| 5 | OUT A | output | Output of channel A; the output goes high impedance when amplifier A is disabled. |
| 6 | -IN A | input | Inverting input of channel A; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V. |
| 7 | +IN A | input | Non-inverting input of channel A; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V. |
| 8 | V- | power_in | Negative power supply (lowest potential); the operating supply [V+] - [V-] is 1.8 V to 5.5 V. |
| 9 | NC | unconnected | No internal connection; the pin may be left floating. |
| 10 | Enable A | input | Enable input for amplifier A; a logic high (above 75% of V+, up to 5.5 V above V-) enables the amplifier, a logic low (within 0.8 V of V-) disables it, and the pin must not be left open. |
| 11 | Enable B | input | Enable input for amplifier B; a logic high (above 75% of V+, up to 5.5 V above V-) enables the amplifier, a logic low (within 0.8 V of V-) disables it, and the pin must not be left open. |
| 12 | NC | unconnected | No internal connection; the pin may be left floating. |
| 13 | +IN B | input | Non-inverting input of channel B; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V. |
| 14 | -IN B | input | Inverting input of channel B; the common-mode input range is (V-) - 0.1 V to (V+) + 0.1 V. |
| 15 | OUT B | output | Output of channel B; the output goes high impedance when amplifier B is disabled. |
| 16 | V+ | power_in | Positive power supply (highest potential); the operating supply [V+] - [V-] is 1.8 V to 5.5 V. |

## CAD (KiCad official)

- Symbol: `OPA2363AIRSVR`
- Footprint: `Package_DFN_QFN:UQFN-16_1.8x2.6mm_P0.4mm`
- 3D model: UQFN-16(1.8x2.6), generated from the KiCad footprint (body from the F.Fab outline, terminals on the pads, 0.55 mm nominal UFQFPN height). Neither the vendor nor KiCad ships a 3D model for this package, so the dimensions are nominal, not the manufacturer's CAD (STEP)
- 3D model files: `opa2363airsvr-etched.step` / `opa2363airsvr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `opa2363airsvr.step` / `opa2363airsvr.glb` are the bare package body.
