Micropower dual op-amp for battery-tight signal chains
The Texas Instruments OPA2336U is a dual CMOS operational amplifier from the MicroAmplifier™ series, packing two rail-to-rail output channels into an 8-SOIC package. It draws 20 µA per channel — the kind of quiescent current that lets a sensor node run for months on a coin cell — and delivers a 100 kHz gain-bandwidth product with a 0.03 V/µs slew rate. The 60 µV input offset voltage keeps the DC error tight enough for precision low-frequency signal conditioning: thermocouple amplifiers, battery-monitor front-ends, or photodiode transimpedance stages where the signal is small and the power budget is smaller.
What the key ratings mean for your BOM
The 100 kHz GBW and 0.03 V/µs slew rate suit DC to low-audio-frequency loops. The 20 µA supply current per channel is the headline; at 2.3 V the total draw for both amplifiers is 40 µA.
Supply range and temperature grade
The OPA2336U operates from 2.3 V to 5.5 V single supply, covering 5 V rails common in portable and industrial designs. The -40°C to 85°C temperature range qualifies it for factory-floor sensor interfaces and outdoor telecom cabinets.
