MC34071DG Description

The MC34071DG from onsemi is a high-performance, general-purpose operational amplifier (op-amp) designed for a wide range of analog applications. Housed in an 8-SOIC package, this single-channel op-amp operates over a 3V to 44V supply range, making it versatile for both low and high-voltage circuits. With a 4.5 MHz gain bandwidth product (GBW) and a 13V/µs slew rate, it delivers excellent signal fidelity and transient response, suitable for precision amplification and signal conditioning. The device exhibits low input bias current (100 nA) and offset voltage (1 mV), ensuring accuracy in sensitive applications. Although marked as obsolete, it remains ROHS3 compliant and REACH unaffected, adhering to environmental standards.
