Web15 feb 2016 · Texas Instruments OPA1622 SoundPlus™ Audio Operational Amplifier is a dual, bipolar-input audio operational amplifier that achieves a very low, 2.8nV/√Hz noise density. This is done with an ultra-low THD+N of -119.2dB at 1kHz while driving a 32Ω load at 100mW output power. Web10 dic 2015 · Ok calculate the output impedance of the opa1622 with a negative feedback of 1k. The negative feedback is sensing the output voltage. It is the open loop output impedance at given frequency and divided by the open loop gain of whatever the frequency your are looking at assuming +1 gain configuration. Typical output impedance is lower …
