5V zero-drift bandwidth ladder for current sense, wearables, battery hardware

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.

5V zero-drift bandwidth ladder (excerpt)

Further catalog tiers: 5 / 9 MHz (COS387/388). Typical Vos max 10 µV, drift 0.005 µV/°C.

Checklist mapped to vendor applications

1. Current sense: shunt drop vs 10 µV Vos; common-mode still in 5V band?
2. Wearable / battery: 18 µA vs 170–425 µA for extra bandwidth.
3. Sensors: 0.35 vs 1.5 vs 3 vs 7 MHz cover signal BW?
4. Channels: 1 / 2 / 4 vs board budget.
5. Package: SOT-23-5 ≠ SOP-8.
6. Samples: request from Jarwey.
