The Texas Instruments RC4558IP is a dual general-purpose operational amplifier in an 8-pin DIP through-hole package.
Operating from a single or split supply spanning 10 V to 30 V total, the RC4558IP fits into designs with standard ±5 V to ±15 V rails.
DC precision and output drive
Input offset voltage is 500 µV typical, and input bias current is 150 nA — adequate for non-precision applications like summing amplifiers or comparator circuits where microvolt-level offset is not critical.
