# TLV274IDR

**Texas Instruments** · Operational Amplifier · SOIC-14

TLV274IDR from Texas Instruments, in a SOIC-14. Pinout and pin descriptions extracted from the manufacturer datasheet by ds2sf; symbol, footprint, and 3D from KiCad-official CAD.

## Pinout

| Pin | Name | Type | Function |
|---|---|---|---|
| 1 | 1OUT | output | Output of op-amp channel 1. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max). |
| 2 | 1IN- | input | Inverting input, channel 1. High-impedance CMOS input (~1000 GΩ differential, 8 pF common-mode capacitance, ~1 pA input bias current). |
| 3 | 1IN+ | input | Noninverting input, channel 1. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V. |
| 4 | VDD | power_in | Positive (highest) supply. Single-supply range 2.7 V to 16 V, or split-supply ±1.35 V to ±8 V. Absolute max 16.5 V. |
| 5 | 2IN+ | input | Noninverting input, channel 2. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V. |
| 6 | 2IN- | input | Inverting input, channel 2. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current). |
| 7 | 2OUT | output | Output of op-amp channel 2. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max). |
| 8 | 3OUT | output | Output of op-amp channel 3. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max). |
| 9 | 3IN- | input | Inverting input, channel 3. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current). |
| 10 | 3IN+ | input | Noninverting input, channel 3. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V. |
| 11 | GND | power_in | Negative (lowest) supply or ground for single-supply operation. All device voltage values (except differential) are referenced to this pin. |
| 12 | 4IN+ | input | Noninverting input, channel 4. High-impedance CMOS input; common-mode input range 0 V to VDD-1.35 V. |
| 13 | 4IN- | input | Inverting input, channel 4. High-impedance CMOS input (~1000 GΩ differential, ~1 pA input bias current). |
| 14 | 4OUT | output | Output of op-amp channel 4. Rail-to-rail output stage; short-circuit output current limited (±100 mA absolute max). |

## CAD (KiCad official)

- Symbol: `TLV274IDR`
- Footprint: `Package_SO:SOIC-14_3.9x8.7mm_P1.27mm`
- 3D model: SOIC-14 (KiCad packages3D, STEP)
- 3D model files: `tlv274idr-etched.step` / `tlv274idr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tlv274idr.step` / `tlv274idr.glb` are the bare package body.

## 3D model downloads

Two STEP files. Same geometry, different body top:

| File | Size | Use it when |
|---|---|---|
| [`tlv274idr.step`](tlv274idr.step) | 195 KB | You want the bare part, or you mark your own boards. |
| [`tlv274idr-etched.step`](tlv274idr-etched.step) | 1.7 MB | You want the part with `TLV274IDR` already on it. |

The marking in the etched file is real recessed geometry cut into the solid, not a
texture or a decal: 463 faces against 237 in the bare model. It
survives export, section views, and rendering in any CAD tool, and it drops straight
into KiCad or Fusion with no extra setup.
