Dual op-amp for signal conditioning and audio paths
Input offset voltage is rated at 2 mV typical, and input bias current at 40 nA.
Commercial temperature grade — indoor and controlled environments
That limits it to indoor, office, or lab equipment where the ambient stays above freezing and below 70°C. Not a candidate for automotive under-hood, outdoor telecom cabinets, or factory-floor enclosures without climate control.
Supply rails and output drive
With a supply span from 10 V to 30 V, the RC4559DG4 works comfortably on ±5 V to ±15 V split rails or a single 12 V to 24 V rail. Each output can deliver 10 mA — enough to drive the next ADC input or a low-power headphone amplifier, but not a speaker or relay coil directly. The 40 nA input bias current is typical for a bipolar-input op-amp; for high-impedance sources (above 100 kΩ), consider a FET-input alternative to avoid offset errors.
For EU-bound designs or global shipping, the ROHS3 compliance removes the need for exemption paperwork.
