# TLE2142AIDR

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

TLE2142AIDR 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 | 1OUT | output | Channel 1 output, nearly rail-to-rail swing of VCC− + 0.1V to VCC+ − 1V and short-circuit current limited internally. |
| 2 | 1IN− | input | Channel 1 inverting input, operating between VCC− − 0.3V and VCC+ − 1.8V without phase reversal. |
| 3 | 1IN+ | input | Channel 1 noninverting input, operating between VCC− − 0.3V and VCC+ − 1.8V without phase reversal. |
| 4 | VCC− | power_in | Negative supply for split-supply operation or ground for single-supply operation (supply range 4V to 44V total). |
| 5 | 2IN+ | input | Channel 2 noninverting input, operating between VCC− − 0.3V and VCC+ − 1.8V without phase reversal. |
| 6 | 2IN− | input | Channel 2 inverting input, operating between VCC− − 0.3V and VCC+ − 1.8V without phase reversal. |
| 7 | 2OUT | output | Channel 2 output, nearly rail-to-rail swing of VCC− + 0.1V to VCC+ − 1V and short-circuit current limited internally. |
| 8 | VCC+ | power_in | Positive supply, with recommended supply voltage up to ±22V (absolute maximum 22V relative to midpoint). |
