TS421
Overview
The TS419 / TS421, is a monaural audio power amplifier driving in BTL mode a 16 or 32 Ω earpiece or receiver speaker. The main advantage of this configuration is to get rid of bulky output capacitors.
- Operating from VCC = 2 V to 5.5 V
- Standby mode active high (TS419) or low (TS421)
- Output power into 16 Ω: 367 mW @ 5 V with 10% THD+N max or 295 mW @ 5 V and 110 mW @ 3.3 V with 1% THD+N max.
- Low current consumption: 2.5 mA max.
- High signal-to-noise ratio: 95 dB (A) at 5 V
- PSRR: 56 dB typ. at 1 kHz, 46 dB at 217 Hz
- Short-circuit limitation
- ON/OFF click reduction circuitry
- Available in MiniSO8 and DFN 3x3
