STH4010 Overview
The STH4010 is a 2.5-W high efficiency filter-free class-D audio power amplifier (class-D amp) in a 1,45 mm × 1,45 mm wafer chip.
STH4010 Key Features
- Maximum Battery Life and Minimum Heat
- Efficiency With an 8-Ω Speaker
- 88% at 400 mW
- 80% at 100 mW
- 2.8-mA Quiescent Current
- 0.5-µA Shutdown Current
- Only Three External ponents
- Optimized PWM Output Stage Eliminates LC Output Filter
- Internally Generated 250-kHz Switching Frequency Eliminates Capacitor and Resistor
- Improved PSRR (-75 dB) and Wide Supply Voltage (2.5 V to 5.5 V) Eliminates Need for a Voltage Regulator
