Features, Applications

LOW (TS421) with 10% THD+N max 295mW @5V and 110mW @3.3V with 1% THD+N max. s LOW CURRENT CONSUMPTION: 2.5mA max s High Signal-to-Noise ratio: 5V s PSRR: 56dB typ. 217Hz s SHORT CIRCUIT LIMITATION s ON/OFF click reduction circuitry s Available MiniSO8 & DFN 3x3 DESCRIPTION The is a monaural audio power amplifier driving in BTL mode or 32 earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky ouput capacitors. Capable of descending to low voltages, it delivers to 220mW per channel (into 16 loads) of continuous average power with 0.2% THD+N in the audio bandwidth from a 5V power supply. An externally controlled standby mode reduces the supply current to 10nA (typ.). The TS419/ TS421 can be configured by external gain-setting resistors or used in a fixed gain version. APPLICATIONS s 16/32 ohms earpiece or receiver speaker driver s Mobile and cordless phones (analog / digital) s PDAs & computers s Portable appliances ORDER CODE

1. All voltage values are measured with respect to the ground pin. 2. Pd has been calculated with Tamb = 25C, Tjunction = 150C.

3. TS419 stands 1.5KV on all pins except standby pin which stands 1KV. 4. Attention must be paid to continous power dissipation (VDD x 300mA). Exposure of the to a short circuit for an extended time period is dramatically reducing product life expectancy.

Components RIN CIN RFEED CS CB Functional Description Inverting input resistor which sets the closed loop gain in conjunction with RFEED. This resistor also forms a high pass filter with CIN (fcl Pi x RIN x CIN)). Not needed in fixed gain versions. Input coupling capacitor which blocks the DC voltage at the amplifier's input terminal Feedback resistor which sets the closed loop gain in conjunction with RIN. AV= Closed Loop Gain= 2xRFEED/RIN. Not needed in fixed gain versions. Supply Bypass capacitor which provides power supply filtering. Bypass capacitor which provides half supply filtering.
