Additional Details

The UTC4558D features a typical open-loop voltage gain of 100 dB, a common-mode rejection ratio (CMRR) of 80 dB, and a slew rate of 0.5 V/μs. It operates from a dual power supply ranging from ±3V to ±18V. The IC is available in DIP-8, SOIC-8, and other surface-mount packages. Applications typically require external resistors and capacitors to set the gain, filter characteristics, and bias conditions. The UTC4558D is a general-purpose operational amplifier suitable for a wide variety of analog circuits. The internal frequency compensation ensures stable operation without external compensation components. The low input bias current minimizes errors caused by input impedance mismatch. The high open-loop gain allows for accurate amplification of weak signals.

Consider using proper decoupling capacitors on the power supply pins to minimize noise and ensure stable operation.
