COSINE Tier-1 distributor Jarwey｜5V zero-drift bandwidth ladder for current sense, wearables, battery hardware
Jarwey is a Tier-1 distributor of COSINE—selection support, datasheets, sampling & small batch, lead-time coordination.
COSINE’s 5V zero-drift class is listed for: current sensing, wearables, sensor amplification, battery-powered smart hardware. Microvolt offset on a battery rail is the main job. The OPA333 SKU article is here; this page is the catalog bandwidth / Iq ladder. High-voltage current sense → 36V zero-drift family.
Metrics follow the 2025 catalog. Request datasheets from Jarwey.
Product features
Microvolt offset, low Iq, RRIO, low noise density, RF immunity.
Applications (vendor-stated)
Current sensing · wearables · sensor amps · battery-powered hardware.

Further catalog tiers: 5 / 9 MHz (COS387/388). Typical Vos max 10 µV, drift 0.005 µV/°C.
Checklist mapped to vendor applications
- Current sense: shunt drop vs 10 µV Vos; common-mode still in 5V band?
- Wearable / battery: 18 µA vs 170–425 µA for extra bandwidth.
- Sensors: 0.35 vs 1.5 vs 3 vs 7 MHz cover signal BW?
- Channels: 1 / 2 / 4 vs board budget.
- Package: SOT-23-5 ≠ SOP-8.
- Samples: request from Jarwey.
