1 / 32 page 1/32 s OPERATING FROM Vcc=2V to 5.5V s STANDBY MODE ACTIVE HIGH (TS419) or LOW (TS421) s OUTPUT POWER into 16 Ω: 367mW @ 5V with 10% THD+N max or 295mW @5V and 110mW @3.3V with 1% THD+N max. s LOW CURRENT CONSUMPTION: 2.5mA max s High Signal-to-Noise ratio: 95dB(A) at 5V s PSRR: 56dB typ. at 1kHz, 46dB at 217Hz s SHORT CIRCUIT LIMITATION s ON/OFF click reduction circuitry s Available in SO8, MiniSO8 & DFN 3x3 DESCRIPTION The TS419/TS421 is a monaural audio power am- plifier driving in BTL mode a 16 or 32 Ω earpiece or receiver speaker. The main advantage of this con- figuration is to get rid of bulky ouput capacitors. Capable of descending to low voltages, it delivers up to 220mW per channel (into 16 Ω loads) of con- tinuous 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 MiniSO & DFN only available in Tape & Reel with T suffix.
