Can I ask to identify this cascaded OpAmp Configuration?

Hi I would Like to ask what is the function of this Op amp conficguration.

There is 2 OpAmp IC1 and IC2.

IC1 and IC2 is cascaded, having the output of IC1 conected to 4.7KOhm R2 resistor, and the other end is connected to negative input of IC2.

IC1 negative terminal is connected to ground. IC2 positive terminal is connected to ground.

IC1 has feedback resistor of 47KOhms R1 Resistor to + terminal of IC1.

IC2 has feedback capacitor of 2,2uF C1 Capacitor to - terminal of IC2.

There is Feedback resistor R3 of 12KOhm from output of IC2 to + terminal of IC1.

IC2 is connected to an inverting amplifier. But I would like to know what is IC1 and IC2 output. Is it a multivibrator?

Thank you.
