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 | OUTPUT 1 | output | Output of op-amp channel 1. Output swings from 0V to VCC-1.5V; source current 20-40mA, sink current 10-20mA at VCC=15V, VO=2V. |+| 2 | INPUT 1- | input | Inverting input of op-amp channel 1. Input bias current ~20nA (typ), input offset current ~5nA. Input voltage range includes ground; do not drive more than 0.3V below GND. |+| 3 | INPUT 1+ | input | Non-inverting input of op-amp channel 1. Input common-mode range 0V to VCC-1.5V; can tolerate up to +32V independent of VCC. |+| 4 | GND | power_in | Ground / negative supply. For single-supply operation tie to 0V; for dual supplies connect to V-. |+| 5 | INPUT 2+ | input | Non-inverting input of op-amp channel 2. Input common-mode range 0V to VCC-1.5V; can tolerate up to +32V independent of VCC. |+| 6 | INPUT 2- | input | Inverting input of op-amp channel 2. Input bias current ~20nA (typ), input offset current ~5nA. Input voltage range includes ground; do not drive more than 0.3V below GND. |+| 7 | OUTPUT 2 | output | Output of op-amp channel 2. Output swings from 0V to VCC-1.5V; source current 20-40mA, sink current 10-20mA at VCC=15V, VO=2V. |+| 8 | VCC | power_in | Positive supply voltage. Single-supply range 3V to 32V (30V recommended max); dual-supply range ±1.5V to ±16V. Supply current 0.5mA (typ) at VCC=5V, 1mA (typ) at VCC=30V. |++## Key specifications++| Parameter | Value |+|---|---|+| Manufacturer | Changjing |+| Package | SOP-8 |+| Category | Op-amp/Cmp |+| Pins | 8 |++## CAD (KiCad official)++- Symbol: `CJ358`+- Footprint: `Package_SO:SOIC-8_3.9x4.9mm_P1.27mm`+- 3D model: SOP-8 (KiCad packages3D, STEP)++## Provenance++Data extracted from the manufacturer datasheet, not a distributor listing:++- **Datasheet:** [Changjing datasheet](docs/cj358-datasheet.pdf) (6 pp, sha256 `176af1babad100e2`, retrieved 2026-08-17, tier: lcsc)+- **Extractor:** `ds2sf` (Claude).
