REMARKS
1.
All measurements, except PSRR measurements, are made with a supply bypass capacitor Cs = 100μF.
2.
External resistors are not needed for having better stability when supply @ Vcc down to 3V. By the
way, the quiescent current remains the same.
3.
The standby response time is about 1μs.
Components
Functional Description
Rin
Inverting input resistor which sets the closed loop gain in conjunction with Rfeed. This resistor also
forms a high pass filter with Cin (fc = 1 / (2 x Pi x Rin x Cin))
Cin
Input coupling capacitor which blocks the DC voltage at the amplifier input terminal
Rfeed
Feed back resistor which sets the closed loop gain in conjunction with Rin
Cs
Supply Bypass capacitor which provides power supply filtering
Cb
Bypass pin capacitor which provides half supply filtering
Cfeed
Low pass filter capacitor allowing to cut the high frequency
(low pass filter cut-off frequency 1 / (2 x Pi x Rfeed x Cfeed))
Rstb
Pull-up resistor which fixes the right supply level on the standby pin
Gv
Closed loop gain in BTL configuration = 2 x (Rfeed / Rin)
