LF253DT from STMicroelectronics, in a SO-8. 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 | OUT1 | output | Output of amplifier 1. Short-circuit protected; typical output swing ±12 V into RL = 2 kΩ at VCC = ±15 V. |
| 2 | IN1- | input | Inverting input of amplifier 1. High-impedance JFET input (Ri ≈ 10^12 Ω); input bias current typ. 20 pA at 25°C. |
| 3 | IN1+ | input | Non-inverting input of amplifier 1. High-impedance JFET input (Ri ≈ 10^12 Ω); common-mode range typ. +15/-12 V at VCC = ±15 V. |
| 4 | VCC- | power_in | Negative supply rail. Operating range VCC = ±3 V to ±18 V (6 to 36 V total supply). Typically tied to -15 V or GND in single-supply designs. |
| 5 | IN2+ | input | Non-inverting input of amplifier 2. High-impedance JFET input (Ri ≈ 10^12 Ω); common-mode range typ. +15/-12 V at VCC = ±15 V. |
| 6 | IN2- | input | Inverting input of amplifier 2. High-impedance JFET input (Ri ≈ 10^12 Ω); input bias current typ. 20 pA at 25°C. |
| 7 | OUT2 | output | Output of amplifier 2. Short-circuit protected; typical output swing ±12 V into RL = 2 kΩ at VCC = ±15 V. |
| 8 | VCC+ | power_in | Positive supply rail. Operating range VCC = ±3 V to ±18 V (6 to 36 V total supply). Typical supply current 1.4 mA (no load). |
