Nano-power op-amp family: wearables, battery hardware, current sense

COSINE catalog nano-power op-amps target wearables, sensor gain, battery-powered smart hardware, and current sensing. Split vs micro-power / shutdown families: stay here when you need RRIO at sub-µA to mid-hundreds µA Iq; see the micro-power family or shutdown family otherwise.

Request datasheets from Jarwey. Evaluate MCP6042 / LMV722 paths only with verification—not pin-to-pin claims.

Product features

Ultra-low quiescent current, rail-to-rail I/O, low noise density, RF immunity.

Applications (vendor-stated)

Wearables · sensor amplification · battery-powered smart hardware · current sensing.

Nano-power op-amp table (representative)

Same catalog page also lists COS6041/6044, COS*379, COS821/822, COS1374/2374, COS721/724—split by Iq vs bandwidth.

Checklist before freeze

1. Wearable / battery: is sleep budget nearer 0.5 µA or hundreds of µA?
2. Sensor / shunt: is 24 kHz enough, or move to the COS722 tier on the same page?
3. Family split: low Iq without SHDN → here; need shutdown pin → shutdown family.
4. Second source: MCP6042 / LMV722 are evaluation anchors only—verify on the bench.
5. Samples & datasheets: request from Jarwey.
