LF353DT

STMicroelectronics · FET InputAmplifiers · SO-8

LF353DT 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 op-amp channel 1. Push-pull output with short-circuit protection; typical short-circuit current 40 mA.
2 IN1- input Inverting input of op-amp channel 1. High-impedance JFET input (~10^12 Ω), typical input bias current 20 pA.
3 IN1+ input Non-inverting input of op-amp channel 1. High-impedance JFET input (~10^12 Ω); common-mode range up to VCC+.
4 VCC- power_in Negative supply rail. Connect to -VCC in dual-supply operation or to GND in single-supply operation. Total VCC range 6-36 V (±3 to ±18 V).
5 IN2+ input Non-inverting input of op-amp channel 2. High-impedance JFET input (~10^12 Ω); common-mode range up to VCC+.
6 IN2- input Inverting input of op-amp channel 2. High-impedance JFET input (~10^12 Ω), typical input bias current 20 pA.
7 OUT2 output Output of op-amp channel 2. Push-pull output with short-circuit protection; typical short-circuit current 40 mA.
8 VCC+ power_in Positive supply rail. Total VCC range 6-36 V (±3 to ±18 V absolute maximum ±18 V per rail). Typical supply current 1.4 mA (no load).

CAD (KiCad official)

  • Symbol: LF353DT
  • Footprint: Package_SO:TI_SO-PowerPAD-8
  • 3D model: SO-8 (KiCad packages3D, STEP)
  • 3D model files: lf353dt-etched.step / lf353dt-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); lf353dt.step / lf353dt.glb are the bare package body.

Provenance

Data extracted from the manufacturer datasheet, not a distributor listing:

  • Datasheet: STMicroelectronics datasheet (15 pp, sha256 ceac07779b59e65c, retrieved 2026-08-17, tier: lcsc)
  • Extractor: ds2sf (Claude). Every pin and dimension is cited to a datasheet page; it refuses to fabricate.
  • CAD: KiCad official libraries (CC-BY-SA 4.0).
