EG4003C

EG Micro · Ambient Light Sensors · SOP-8

EG4003C from EG Micro, in a SOP-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 1OUT output Output of the internal first-stage op-amp (OP1). Used as the feedback node for the external gain-setting network (R2, R3, C3) driving the inverting input 1IN-.
2 1IN- input Inverting input of the internal first-stage op-amp (OP1). The PIR/microwave signal is AC-coupled here through C2/R2; overall analog gain A = A1*A2 = (R3/R2)*30 (typical 9000).
3 VC input Trigger-inhibit input. When V(VC) < 0.2VDD triggering is disabled and OUT is forced low; when V(VC) > 0.2VDD the trigger path is enabled and OUT follows Vs. Typically driven by a CdS/LDR divider for dusk-only operation.
4 A input Retrigger mode select. A='1' (tied to VDD) enables retriggerable mode (Tx timer restarts on each Vs pulse during Tx). A='0' (tied to GND) selects non-retriggerable mode. VAH=3.5 V min @VDD=5 V; VAL=1 V max @VDD=5 V.
5 GND power_in Device ground reference (0 V).
6 OUT output Active-high control signal output driving the load (relay, transistor, MCU). Drive capability ±25 mA at VDD=5 V and ±10 mA at VDD=3 V; VOH=4.5 V min @ILOAD=10 mA / VDD=5 V.
7 CT passive Oscillator timing node. Connect an external capacitor CT to GND and a pull-up resistor RT (>=100 kΩ) to VDD; Tosc ≈ 0.4·RT·CT·RT/(RT-20k). Example: RT=100 kΩ, CT=1 nF → Tosc≈50 μs (f≈20 kHz). Sets Tx and Ti timer periods.
8 VDD power_in Positive supply input, +3 V to +6 V operating range (7 V absolute max). Quiescent current typ 35 uA @3 V, 65 uA @5 V.

CAD (KiCad official)

  • Symbol: EG4003C
  • Footprint: Package_SO:SOIC-8_3.9x4.9mm_P1.27mm
  • 3D model: SOP-8 (KiCad packages3D, STEP)
  • 3D model files: eg4003c-etched.step / eg4003c-etched.glb carry the MPN laser-etched on the die in a toggleable Adom.LaserEtch group (Fusion-ready); eg4003c.step / eg4003c.glb are the bare package body.

3D model downloads

Two STEP files. Same geometry, different body top:

File Size Use it when
eg4003c.step 122 KB You want the bare part, or you mark your own boards.
eg4003c-etched.step 1.8 MB You want the part with EG4003C already on it.

The marking in the etched file is real recessed geometry cut into the solid, not a texture or a decal: 447 faces against 147 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.

Provenance

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

  • Datasheet: EG Micro datasheet (14 pp, sha256 b037c27db8b148b3, 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).
