Typical application for the TS488-TS489
Application component information
Inverting input resistor that sets the closed loop gain in conjunction with R
This resistor also forms a high pass filter with C
Input coupling capacitor that blocks the DC voltage at the amplifier’s input terminal.
Feedback resistor that sets the closed loop gain in conjunction with R
A
Supply output capacitor that provides power supply filtering.
Bypass capacitor that provides half supply filtering.
Output coupling capacitor that blocks the DC voltage at the load input terminal.
This capacitor also forms a high pass with R
