DESCRIPTION
The TS419/TS421 is a monaural audio power amplifier driving in BTL mode a 16 or 32Ω earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky output capacitors.
■ OPERATING FROM Vcc=2V to 5.5V
■ STANDBY MODE ACTIVE HIGH (TS419) or
LOW (TS421)
■ OUTPUT POWER into 16Ω: 367mW @ 5V
with 10 THD+N max or 295mW @5V and
110mW @3.3V with 1 THD+N max.
■ LOW CURRENT CONSUMPTION: 2.5mA max
■ High Signal-to-Noise ratio: 95dB(A) at 5V
■ PSRR: 56dB typ. at 1kHz, 46dB at 217Hz
■ SHORT CIRCUIT LIMITATION
■ ON/OFF click reduction circuitry
■ Available in SO8, MiniSO8 & DFN 3x3
APPLICATIONS
■ 16/32 ohms earpiece or receiver speaker driver
■ Mobile and cordless phones (analog / digital)
■ PDAs & computers
■ Portable appliances
