14.4 General remarks
T
20 kHz.
The Single-Ended (SE) application diagram is shown in
The capacitor value of C3 in combination with the load impedance determines the low
frequency behavior. The total harmonic distortion + noise as a function of frequency was
measured with a low-pass filter of 80 kHz. The value of the capacitor C2 influences the
behavior of the PSRR at low frequencies; increasing the value of C2 increases the
performance of PSRR.
The frequency characteristics can be adapted by connecting a small capacitor across the
feedback resistor. To improve the immunity of HF radiation in radio circuit applications, a
small capacitor can be connected in parallel with the feedback resistor (56 k ); this
creates a low-pass filter.
