TS419 TS421 360mW MONO AMPLIFIER WITH STANDBY MODE s OPERATING FROM Vcc=2V to 5.5V s STANDBY MODE ACTIVE HIGH (TS419) or s OUTPUT POWER into 16: 367mW @ 5V LOW (TS421) 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 amplifier driving in BTL mode a 16 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 up 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 Part Number Temp.
