TPA6203A1DGNR

Overview

The TPA6203A1DGNR is a 1.25-W mono fully differential audio power amplifier in an 8-pin MSOP package. It operates from a single supply voltage ranging from 2.5 V to 5.5 V and delivers 1.25 W into an 8-ohm load at 5 V with 1% THD. The device draws 1.7 mA typical quiescent current and features shutdown control consuming less than 10 μA. It includes internal bias circuitry, eliminating the need for input coupling capacitors in differential configurations.

Feature Summary

• Fully differential architecture reduces RF rectification interference and eliminates input coupling capacitors
• High power supply rejection ratio improves performance in noisy environments
• Fast startup time minimizes audible pop noise during activation
• Optional bypass capacitor design reduces external component count

Applications

• Wireless handsets
• Cellular phones
• Personal digital assistants
