# TLE2426CDR

**Texas Instruments** · Voltage Reference · SOIC-8

TLE2426CDR 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 | OUT | output | Virtual-ground output that holds one-half the input voltage (VO/VI = 0.5), rated for source and sink current with output current limited to ±80 mA absolute maximum. |
| 2 | COMMON | power_in | Common (ground) reference pin for the device; the output is referenced to this pin at one-half the input voltage. |
| 3 | IN | power_in | Supply input, specified at 4 V to 40 V in recommended operating conditions with a 40 V absolute maximum continuous input voltage. |
| 4 | NC | unconnected | No internal connection. |
| 5 | NC | unconnected | No internal connection. |
| 6 | NC | unconnected | No internal connection. |
| 7 | NC | unconnected | No internal connection. |
| 8 | NOISE REDUCTION | passive | Noise-reduction pin for an external capacitor CNR, which lowers output noise (120 µV rms with CNR = 0 to 30 µV rms with CNR = 1 µF) and improves line ripple rejection. |

## CAD (KiCad official)

- Symbol: `TLE2426CDR`
- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`
- 3D model: SOIC-8 (KiCad packages3D, STEP)
- 3D model files: `tle2426cdr-etched.step` / `tle2426cdr-etched.glb` carry the MPN laser-etched on the die in a toggleable `Adom.LaserEtch` group (Fusion-ready); `tle2426cdr.step` / `tle2426cdr.glb` are the bare package body.
