Jarwey is a Tier-1 distributor of COSINE—selection support, datasheets, sampling & small batch, lead-time coordination.

COSINE current shunt monitors target sensors, battery management, and power management. Use this family for wide-CM shunt sensing with fixed or adjustable gain; discrete diff amps stay in the precision/zero-drift op-amp notes.

Datasheets from Jarwey. INA180 / INA138 are common second-source evaluation anchors—verify before lock-in.

Product features

Low offset, high accuracy, zero-drift oriented, low power, wide common-mode range.

Applications (vendor-stated)

Sensors · battery management · power management.

Also listed: COS211–215 and COSINA180A1/A3/A4 gain options.

Checklist before freeze

BMS / power: map shunt and full-scale to the gain tier.
Common mode: does -0.3–25 V cover high-side sensing?
Supply: need up to 25 V VCC → COS210; 5.5 V logic → INA180/138 tier.
Adjustable vs fixed: prototype with COSINA138, freeze fixed gain for volume.
Samples: request from Jarwey.
