(TOP VIEW OF PCB)
TPA2037D1 Mono Class-D Audio Amplifier• +6 dB Fixed Gain• Integrated Image Reject Filter for DAC Noise
Reduction scale package (WCSP). The device requires only one
external component.
• Low Output Noiseof20 mV
Low Quiescent Currentof 1.5 mA Features like 95% efficiency, 1.5 mA quiescent
current, 0.1 mA shutdown current, 81-dB PSRR,
• Differential Input Impedanceof 300 kΩ 20mV output noise, and improved RF immunity make
• Auto-Recovering Short-Circuit Protection the TPA2037D1 class-D amplifier ideal for cellular
Thermal-Overload Protection handsets.A start-up timeof4 ms withno audible pop
makes the TPA2037D1 ideal for PDA and
• Filter-Free Mono Class-D Amp smart-phone applications.
• 9-Ball 1,21 mm× 1,16 mm 0,4mm Pitch WCSP
