DESCRIPTION The TS4990 has been designed for demanding audio applications such as mobile phones and to minimize the number of external components. This Audio Power Amplifier is capable of delivering 1W of continuous RMS Ouput Power into an 8 load @ 5V. An externally controlled standby mode control reduces the supply current to less than 10nA. It also includes an internal thermal shutdown protection. The unity-gain stable amplifier can be configured by external gain setting resistors.

Components Rin Cin Rfeed Cs Cb Cfeed Gv
Functional Description Inverting input resistor which sets the closed loop gain in conjunction with Rfeed. This resistor also form a high pass filter with Cin (fc = 1 / (2 x Pi x Rin x Cin)) Input coupling capacitor which blocks the DC voltage at the amplifier input terminal Feed back resistor which sets the closed loop gain in conjunction with Rin Supply Bypass capacitor which provides power supply filtering Bypass pin capacitor which provides half supply filtering Low pass filter capacitor allowing to cut the high frequency (low pass filter cut-off frequency 1 / (2 x Pi x Rfeed x Cfeed)) Closed loop gain in BTL configuration = 2 x (Rfeed / Rin)
REMARKS 1. All measurements, except PSRR measurements, are made with a supply bypass capacitor Cs = 1F. 2. The standby response time is about 1s.
