REMARKS
1.
All measurements, except PSRR measurements, are made with a supply bypass capacitor Cs = 1μF.
2.
The standby response time is about 1μs.
Components
Functional Description
Rin
Inverting input resistor which sets the closed loop gain ( when GS = high) in conjunction with the inter-
nal feedback resistor Rfeed. This resistor also forms a high pass filter with Cin1
Fc = 1 / (2 x Pi x Rin x Cin1)
Cin1
Input coupling capacitor which blocks the DC voltage at the amplifier input terminal In1
Cin2
Input coupling capacitor which blocks the DC voltage at the amplifier input terminal In2. This capacitor
also forms a high pass filter with Zin (internal input impedance when Gs = Low
Fc = 1 / (2 x Pi x Zin x Cin2)
Cs
Supply Bypass capacitor which provides power supply filtering (Recommended value = 1μF)
Cb
Bypass pin capacitor which provides half supply filtering (Recommended value = 1μF)
Gv
Closed loop gain in BTL configuration
When Gs = Low, Gv = 2 or 6dB
When GS = high, Gv = 2 x (Rfeed / Rin). Rfeed value see Electrical Characteristics.
