The LM358ADR: It is specified for the commercial temperature range of 0°C to 70°C, making it suitable for controlled indoor environments and bench-level instrumentation. For a unity-gain buffer, the full-power bandwidth is roughly 48 kHz; above that, the output slew-rate limits the undistorted swing. The 2 mV typical input offset voltage and 15 nA input bias current are adequate for DC-coupled signals from moderate-impedance sources (under 100 kΩ).
Supply rail and power budget
Each amplifier draws 500 µA quiescent current, so the dual-channel device consumes 1 mA typical from the rail — a light load that keeps the thermal rise negligible in the SOIC-8 footprint.
